I recently installed Yosemite, and am now trying to upgrade all of my brew installs (brew update, then brew upgrade). After remembering to do xcode-select --install, I finally got all of my installs upgraded except for encfs and osxfuse (encfs depends on osxfuse). Now, when trying to upgrade, I get the following results (entirety included because it's not that big):

▶ brew upgrade                                                   
==> Upgrading 2 outdated packages, with result:
encfs 1.7.5_1, osxfuse 2.7.1
==> Upgrading encfs
==> Installing encfs dependency: osxfuse
==> Cloning https://github.com/osxfuse/osxfuse.git
Updating /Library/Caches/Homebrew/osxfuse--git
==> Checking out tag osxfuse-2.7.1
==> ./build.sh -t homebrew -f /usr/local/Cellar/osxfuse/2.7.1

OSXFUSEBuildTool()            : supported platforms: 10.9 10.10
OSXFUSEBuildTool()            : building OSXFUSE kernel extension and tools

Naturally, I've been to the troubleshooting page, and was still not able to solve my problems (although it might've helped me solve problems with earlier formulae). The results of brew doctor are:

▶ brew doctor

Warning: Broken symlinks were found. Remove them with `brew prune`:

Warning: Unbrewed dylibs were found in /usr/local/lib.
If you didn't put them there on purpose they could cause problems when
building Homebrew formulae, and may need to be deleted.

Unexpected dylibs:

Warning: You have unlinked kegs in your Cellar
Leaving kegs unlinked can lead to build-trouble and cause brews that depend on
those kegs to fail to run properly once built. Run `brew link` on these:

I tried manually setting DEVELOPER_DIR:

▶ export DEVELOPER_DIR=/Applications/Xcode.app/Contents/Developer

That did not make any difference. Does anybody have any suggestions for how I can fix this?

    Have you tried updating XCode? You can download it here

  • @pczora, that did the trick. I'd noticed that brew doctor had suggested it, but (a) didn't know off-hand how to download it, and (b) was skeptical it would help, so didn't pursue (a). Thanks! Make your comment an answer, and I'll accept it. Oct 20, 2014 at 14:09

Upgrading Xcode to 6.1 with the link provided by pczora in fact resolved this problem for me: https://developer.apple.com/downloads/download.action?path=Developer_Tools/xcode_6.1/xcode_6.1.dmg
