Hello,
I see the same problem. Notes for Debug:

• Trying to install the kraken package from homebrew-science with:
  brew install kraken
• Recently upgraded to El Capitan from Yosemite
• Ran xcode-select --install
• brew update at the latest (run several times)
• brew doctor clean except for warnings about tcl libs in /usr/local

And my brew config

Hi,

Thanks for the response. I was running
brew install gubbins

Instructions here: https://github.com/sanger-pathogens/gubbins/blob/master/INSTALL.md#osx---mavericks-109--yosemite-1010--el-capitan-1011

OSX - Mavericks (10.9) & Yosemite (10.10) & El Capitan (10.11)

Install HomeBrew. It requires a minimum of Xcode 5.1.1 (xcodebuild -version). Then run:

brew tap homebrew/science
brew install gubbins

Thanks! That's sufficient information to reproduce the issue! It's caused by some refactoring we've done recently. Sorry that this is causing some problems. I won't be able to fix this myself (it's way too late where I am), but I'll try to leave enough information for some other maintainer to pick this up:

• The method non_apple_gcc_version lives in OS::Mac, but is accessed via @versions == DevelopmentTools in CompilerSelector#compiler_version (in compilers.rb). This needs to be addressed somehow.
• The method clear_version_cache in os/mac.rb also needs some attention. It clears caches that are mostly somewhere else now and thus the method no longer works as intended.

This appears to break Imagemagick compilation too.

[nomoon]

Is there a way to rollback to a functional version of Homebrew?

[ilovezfs]

@nomoon cd /usr/local ; git reset --hard @{2.days.ago} (or whatever the minimum that is required) and add HOMEBREW_NO_AUTO_UPDATE=1 to your profile temporarily

[UniqMartin]

Everyone: The bug should have been fixed by https://github.com/Homebrew/brew/commit/5c1f463ac0f1ac8b3dffc5d235071f9759aa5633. Please brew update and try again. Closing as resolved, but happy to reopen if there's still an issue. Thanks!

[UniqMartin]

[…] and add HOMEBREW_NO_AUTO_UPDATE=1 to your profile temporarily.

@ilovezfs This shouldn't be necessary. The auto-update code isn't yet switched on by default.

[ilovezfs]

@UniqMartin Ah, so the apocalypse hasn't started yet then.

[MikeMcQuaid]

@ilovezfs Currently the only person it is annoying is me (and I wrote it).
