Dupe of #281, #285, #286, etc :)

Thanks for responding. But when I followed the dupe issues, I'm not sure what the solution to the failed build is. Shouldn't a closing an issue mean that rbenv no longer has the problem?

brew install apple-gcc then install. It's an issue with this patchlevel of 1.9.3, unfortunately.

I believe the actually commands you want are:

brew tap homebrew/dupes
brew install apple-gcc42

Thanks @sferik 😁

Yep you need apple-gcc42. There is no apple-gcc formula in Homebrew.

Setting CFLAGS=-Wno-error=shorten-64-to-32 fixes this too.
