thank you for your kind reply.  I have already tried changing umask. 
The vmware filesystem has its own interpretation of permissions and 
access which bears absolutely no resemblance to either the UNIX or the 
NT models.  It feeds false data into the system and well, we get to have 
this conversation.  :-)

I'm currently changing permissions afterwards and that's a source of 
installation breakage because the same information is stored in multiple 
places.  I might be able to unify things if I can figure out how to make 
all components reference everything in a setup.cfg file.

your suggestion about modifications isn't all that horrible because I'm 
already doing a significant amount of work that isn't covered by the 
distutils code as documented.  thank you for the pointers to additional 
functionality that might be useful to me.
