Haskell: tasty-ant-xml is broken with ghc7103

[woehr]

Issue description

When trying to build tasty-ant-xml, the following error is reported.

Configuring tasty-ant-xml-1.0.4...
Setup: At least the following dependencies are missing:
directory >=1.2.6.2, filepath >=1.4.1.0
builder for ‘/nix/store/9c37m8ffxmplxgg2in95gcwli758vs1z-tasty-ant-xml-1.0.4.drv’ failed with exit code 1

Steps to reproduce

nix-env -i -A haskell.packages.ghc7103.tasty-ant-xml -f <nixpkgs>

Technical details

• System: Arch Linux (uname -r -> 4.8.13-1-ARCH)
• Nix version: nix-env (Nix) 1.11.6
• Nixpkgs version: "17.03pre-git" (commit 305e3e2)

I'll add that I'm happy to submit a pull request fixing this, I'm just not sure what to do to fix it.

@woehr According to https://github.com/peti/nixpkgs/blob/master/pkgs/development/haskell-modules/configuration-ghc-7.10.x.nix directory and filepath packages are disabled but I don't know why.
Maybe @peti can help you.

[peti]

directory and filepath are core libraries shipped by GHC. Apparently, current versions of tasty-ant-xml no longer support GHC 7.x.

[woehr]

I suppose overriding the ghc7103 package set with an older version would be the best solution then?

@ocharles appears to be the author/maintainer, would you mind commenting?

[peti]

Generally speaking, the ghc7103 is not a supported package set, i.e. we don't necessarily make an effort to keep everything in there compiling. If someone were to provide a PR that remedies this particular issue, then we'd happily merge it, but keeping an open issue around on Github seems like overkill (since no Nixpkggs maintainer is going to care about it). Therefore, I'm closing this issue and encourage anyone who cares about this build to submit a PR that fixes it.
