No, I just tried that (and then realized that it wouldn't make a difference 
anyways since bdist_rpm runs the build in a separate directory). I noticed that 
the rpm-tmp.* file is a shell script that appears to be what is executed for the 
bdist_rpm. The actual command that gets executed is this:

   env CFLAGS="$RPM_OPT_FLAGS" python setup.py build

That's probably the problem; it's missing the other commands (and since I 
actually had --fcompiler options on some of those commands, that's *really* 
annoying). I'm not too familiar with RPM builds, though, so I don't know which 
component is to blame; likely numpy.distutils should be properly setting up the 
dependency chain of commands such that "python setup.py build" does everything 
correctly. Please enter a ticket in the numpy Trac describing the problem:
