I've updated to OS X Mountain Lion. Update has removed all of my python and apache modules including mod_wsgi.

Now I'm trying to recompile mod_wsgi (it compiled without problems on Lion).

I use source code from here: http://code.google.com/p/modwsgi/wiki/DownloadTheSoftware?tm=2

./configure creates Makefile without problems:

$ ./configure
checking for apxs2... no
checking for apxs... /usr/sbin/apxs
checking Apache version... 2.2.22
checking for python... /usr/bin/python
configure: creating ./config.status
config.status: creating Makefile

But make returns error:

$ make
/usr/sbin/apxs -c -I/System/Library/Frameworks/Python.framework/Versions/2.7/include/python2.7 -DENABLE_DTRACE -DMACOSX -DNDEBUG -DNDEBUG -DENABLE_DTRACE  -Wc,'-arch x86_64' mod_wsgi.c -Wl,-F/System/Library/Frameworks -framework Python -u _PyMac_Error /System/Library/Frameworks/  -arch x86_64 -ldl  -framework CoreFoundation

I solved this problem while writting question:

For some reason /Applications/Xcode.app/Contents/Developer/Toolchains/OSX10.8.xctoolchain/ folder (containing Xcode Command Line Tools) is here: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain

To fix the problem:

$ sudo ln -s /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/ /Applications/Xcode.app/Contents/Developer/Toolchains/OSX10.8.xctoolchain

Greg Bair suggestion for Mavericks:

$ sudo ln -s /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/ /Applications/Xcode.app/Contents/Developer/Toolchains/OSX10.9.xctoolchain

This creates symlink to the right folder.

    Should be highlighted that this is an issue with apxs build configuration that Apple supplied as far as I know and nothing to do with mod_wsgi. It came up prior to Mountain Lion being released and someone provided feedback to Apple somehow, but Apple didn't fix it. It is likely that this issue would affect any attempt to build Apache modules using apxs and not just mod_wsgi. Commented Jul 29, 2012 at 23:50
  • Problem I submited seems to be make utilit related. For some reason it thinks that compiler (gcc) is situated in other folder. It is simply fixable by creating symlink (see my answer for details). sudo make install after that also works. Commented Jul 30, 2012 at 3:07
  • Presuming same file location as older MacOS X, the issue is going to be in definitions in /usr/share/httpd/build/config_vars.mk which apxs uses. Commented Jul 30, 2012 at 3:22
  • As @GrahamDumpleton suggests, this solution also fixes make problems with mod_fastcgi v2.4.6. Commented Oct 9, 2012 at 13:05

    Note that this also works for Mavericks, but it would be $ sudo ln -s /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/ /Applications/Xcode.app/Contents/Developer/Toolchains/OSX10.9.xctoolchain

Ran into the same problem, however creating the symlink did not solve it for me. What did work was adding the flag --disable-framework to the ./configure command. See the gist for more details.
