I was able to use a workaround

brew install texinfo && brew link texinfo --force

$ brew install texinfo
==> Downloading https://homebrew.bintray.com/bottles/texinfo-6.0.yosemite.bottle.1.tar.gz
Already downloaded: /Library/Caches/Homebrew/texinfo-6.0.yosemite.bottle.1.tar.gz
==> Pouring texinfo-6.0.yosemite.bottle.1.tar.gz
==> Caveats
This formula is keg-only, which means it was not symlinked into /usr/local.

Software that uses TeX, such as lilypond and octave, require a newer version
of these files.

$ brew link texinfo --force
Linking /usr/local/Cellar/texinfo/6.0... 28 symlinks created

but I'm curious if there's another solution that doesn't involve overwriting links in /usr/bin, which may be considered a bad practice on OS X.

• You can add the original install location of makeinfo to exec-path in Emacs.
• Or you can add (:name flycheck :build (("/wherever/makeinfo" "-o" "doc/flycheck.info" "doc/flycheck.texi"))) to your el-get-sources.
• Or you can avoid building the texinfo manual altogether with (:name flycheck :build (progn nil) :info nil)

Using this workaround #2306 (comment), I now run into another error.

When I try to run flycheck-mode, I get the following in the Messages buffer

Eager macro-expansion failure: (file-error "Cannot open load file" "no such file or directory" "let-alist") [2 times]
progn: Cannot open load file: no such file or directory, let-alist

[syohex]

let-alist issue was fixed at #2302. Please upgrade el-get and try again. Or upgrade Emacs because let-alist is a core package now.

[mstorus]

@syohex I ran el-get-self-update and tried el-get-install flycheck and it still fails for me with the same errors as posted originally #2306 (comment).
I already have GNU Emacs 25.0.50.1 , is that version recent enough?

[npostavs]

What do you see when you run M-x el-get-describe let-alist?

[syohex]

I already have GNU Emacs 25.0.50.1 , is that version recent enough?

If (require 'let-alist) does not raise error, it is enough recent version.

[mstorus]

M-x el-get-describe let-alist

let-alist is an `el-get' package.  It is built-in since Emacs 25.0.50.

Description: Easily let-bind values of an assoc-list by their names.
The package is built-in since Emacs 25.0.50.
Installed in `/Users/my_user/.emacs.d/el-get/let-alist/'.

Full definition in `/Users/my_user/.emacs.d/el-get/el-get/recipes/let-alist.rcp':
(:name let-alist
       :description "Easily let-bind values of an assoc-list by their names."
       :builtin "25.0.50"
       :type elpa
       :url "https://elpa.gnu.org/packages/let-alist.html")

(require 'let-alist)

File error: Cannot open load file, no such file or directory, let-alist

[npostavs]

Okay, so the problem is that you have an Emacs new enough that el-get thinks let-alist is builtin, but old enough so that it's actually not. Update your Emacs, or as a workaround add (:name let-alist :builtin nil) to your el-get-sources.

[mstorus]

I downgraded my emacs to GNU Emacs 24.5.1 (this should make Emacs old enough such that el-get is not confused about the existence of let-alist).

Now I get an error about seq when I try to M-x flycheck-mode

eval-buffer: Cannot open load file: no such file or directory, seq

[syohex]

I cannot reproduce with Emacs 24.5.1. Could you try again after removing flycheck ?

(setq-default user-emacs-directory default-directory)

(add-to-list 'load-path (locate-user-emacs-file "el-get/el-get"))
(unless (require 'el-get nil 'noerror)
  (with-current-buffer
      (url-retrieve-synchronously
       "https://raw.githubusercontent.com/dimitri/el-get/master/el-get-install.el")
    (goto-char (point-max))
    (eval-print-last-sexp)))

• Open above file with emacs -Q
• M-x eval-buffer
• M-x el-get-install [RET] flycheck

Then seq is installed and M-x flycheck-mode works well.

[npostavs]

If you have kept your ~/.emacs.d/el-get/ from before, then you may to M-x el-get-reinstall seq.
