It sounds like easy_install needs to clear the zipimport directory cache, 
or at least remove any entry corresponding to the file it's installing, in 
the case where it's overwriting an existing file.

As for the SOURCES.txt problem, it seems to be a quirk of the way the 
distutils FileList class works, such that if a file doesn't exist before 
SOURCES.txt is built, it doesn't end up listed in SOURCES.txt.  So, I'll 
have to add a workaround for that as well.

Thanks for taking the time to follow up on this.
