/usr/bin/python* should already exist, they are part of the system.  That's not the problem.

The problem is that /usr/bin is NOT in the PATH in an OS X application.  Applications have essentially no environment at all, but they do understand environment variables.  Applications are in their own world, so to speak.  There is a hidden mechanism for setting Application environment, but I don't want to spread that as it is cluncky to use (need 3rd party apps for a nice GUI front end), and is not well documented, if at all.

You got your symlinking idea backwards, but it does give me an idea for a workaround:

ln -s /usr/bin/python2.6 /Applications/Qgis.app/Contents/MacOS/bin/python

This puts a symlink to the system python in the Qgis application bin, which should be in the PATH in the Qgis environment.
