[Numpy-discussion] numpy v1.2.0 vs 1.2.1 and setup_tools

v1.3.0b1 has the same problem - setup_tools doesn't seem to recognize
that numpy is already installed in the system's site-packages directory.

Maybe I should add that I'm using virtualenv to generate a test environment
which includes the systems site-packages; setup_tools does seem recognize 
other packages which are only available there (e.g., scipy or netCDF4 if 
specified as a requirement for the install... strange. It also doesn't seem 
to work for tables (2.1, so not the newest version)).

Any ideas on what might be going on?

Thanks a lot,
