[py-dev] setuptools / undoing 0.9.1 PATH hacks (Re: 0.9.2 alpha eggs - please test)

[holger krekel]

Hi Harald, Ralf, 

so i created an egg with a function that tries to undo 
the path changes done with 0.9.1.  I checked that the
code works but i think that setuptools does not execute
my code at runtime, only at bdist_egg time.  I guess 
i need to investigate how i can have some code executed
at install time.  Anybody has hints? 

best, 

holger
