[Hervé Coatanhay]

New submission from Hervé Coatanhay :

On a fresh install from mercurial on macosx.

./python -SE -m sysconfig --generate-posix-vars
Could not find platform dependent libraries 
Consider setting $PYTHONHOME to [:]
Assertion failed: (compact->utf8_length == 0), function 
_PyUnicode_CheckConsistency, file Objects/unicodeobject.c, line 369.
make: *** [Lib/_sysconfigdata.py] Abort trap: 6

This is reproduced with the following mercurial changesets:
