Conflict between python used by vim and by YouCompleteMe

Question

YCM does not work for the reason given above. When I type :python import sys; print sys.version I obtain:

2.7.9 (default, Dec 13 2014, 15:13:49)
[GCC 4.2.1 Compatible Apple LLVM 6.0 (clang-600.0.56)]

but when I compiled YCM, I set it up to use /System/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7. Doing ./python2.7 --version in this folder returns 2.7.10.

I figured I could recompile vim and make it use the same python in /System/Library/Frameworks/Python.framework/Versions/2.7/bin, but I don't see a way to do so. The option --with-python-config-dir=PATH doesn't seem to do much. In fact I can see in the config.log

configure:5872: checking for python
configure:5890: found /usr/bin/python

It looks like it will use also /System/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7, but when I compile and type :python import sys; print sys.version I still get 2.7.9. The python in /usr/bin/python is also 2.7.10 and it's not a symlink to /System/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7. This could be conflicting I guess. I also wanted to see where the python vim is using is by typing python import sys; print sys.executable, but this returns the vim bin, not python. Any suggestions? Thanks.

I was able to solve this issue by using the command lsof -p PID. This gave me the python vim was using (which I couldn't find with sys.executable). Then I realized I was including this directory in DYLD_FRAMEWORK_PATH in my .bash_profile. I just deleted it and vim could pick up the correct python version.
