$ mkdir -p ~/lib
$ cd ~/lib
$ ln -s ../.pyenv/versions/2.7.11/lib/libpython2.7.dylib
$ ln -s ../.pyenv/versions/3.4.4/lib/libpython3.4m.dylib

Great resource, thank you very much! Question about the .dylib bit.

How does Python(s) and Vim know where to find the .dylib files. In your case, ~/lib is not a standard LD path?

~/lib/libpython2.7.dylib -> ../.pyenv/versions/2.7.11/lib/libpython2.7.dylib
~/lib/libpython3.4m.dylib -> ../.pyenv/versions/3.4.4/lib/libpython3.4m.dylib

Thanks.
