Vim failing to compile with python on OS X

I've been trying to compile vim 7.3 with python 2.7 support on mac OS X 10.6. Vim itself compiles fine, but the embedded python not so much.

The steps I've taken:

hg clone https:/vim.googlecode.com/hg/ vim
cd vim/src
./configure --without-x --disable-gui --disable-darwin \
            --enable-pythoninterp --with-features=huge
make
make install

That gives me a working vim but without python.

The auto/config.log indicates there's a file error:

configure:5387: checking if compile and link flags for Python are sane
configure:5404: gcc -o conftest -g -O2 
     -I/Library/Frameworks/Python.framework/Versions/2.7/include/python2.7

configure:5408: result: no: PYTHON DISABLED

I get this error whether I run configure with or without the --with-python-conf-dir option. It looks like the -u _PyMac_Error Python.framework/Versions/2.7/Python is the source of the problem, but I'm not sure where to go from here.

Any suggestions?

Turns out the bug is actually in the Python Makefile, believe it or not.

Open the file

/usr/local/Cellar/python/2.7.2/Frameworks/Python.framework/Versions/2.7/lib/python2.7/config

or whatever the appropriate path is for you, and search for PyMac_Error. It should be on the line defining LINKFORSHARED, and on this line you need to change PYTHONFRAMEWORKDIR to PYTHONFRAMEWORKINSTALLDIR. Then go back to your vim source and ./configure, everything should go smooth.

Also make sure you symlink OS X's Python Frameworks to the ones in the Homebrew Cellar:

/Library/Frameworks/Python.framework/Versions/2.7
/Library/Frameworks/Python.framework/Versions/Current
/System/Library/Frameworks/Python.framework/Versions/2.7
/System/Library/Frameworks/Python.framework/Versions/Current

should all point to

/usr/local/Cellar/python/2.7.2/Frameworks/Python.framework/Versions/2.7

Not really sure why I had it in so many places, or if that's bad, but there it is.

It's not a straight answer to your question, but installing macports and running sudo port install vim +python27 is one way to get there.
