[Bf-python] bug (?) in Python path

[Jacques Guignot]

When I launch blender, I have a warning :

In BPY_start_python
Could not find platform independent libraries <prefix>
Could not find platform dependent libraries <exec_prefix>
Consider setting $PYTHONHOME to <prefix>[:<exec_prefix>]
'import site' failed; use -v for traceback
initBlenderApi2_2x


and my python path is very strange :
['/home/flepied/tmp/rpm/python-2.2.2-6mdk-root/usr/lib/python2.2/', 
'/home/flepied/tmp/rpm/python-2.2.2-6mdk-root/usr/lib/python2.2/plat-linux-i386', 
'/home/flepied/tmp/rpm/python-2.2.2-6mdk-root/usr/lib/python2.2/lib-tk', 
'/home/flepied/tmp/rpm/python-2.2.2-6mdk-root/usr/lib/lib-dynload']

none of these directories are on my filesystem...

BlenPyGurus, any idea ?
