Comment (by kyngchaos):

 > On the other hand, similarly to what I did with Grass, I can use
 install_name_tool to change the reference inside the library.

 Except that there is no guarantee that the same version of Python will be
 found by the default python detection as is installed in MacPorts.
 Linking to v2.5 and then telling Qgis to load v2.6 will likely cause
 trouble.

 > With -framework Python, ld accepts also -F {FRAMEWORK_PATH} that specify
 alternate frameworks path searched before the standard path.

 The way cmake works with libraries, it probably links the framework binary
 directly, so -F will have no effect.  ie instead of:

 {{{
 -F /Library/Frameworks -framework Python
 }}}

 it will link:

 {{{
 /Library/Frameworks/Python.framework/Versions/2.5/Python
 }}}

 This is so that (I'm guessing) cmake can make sure the exact library
 binary that you want, or an internal library binary, is linked and -L/-F
 paths don't confuse things.
