using Pmw with McMillan installer

[Howard Lightstone]

I am trying to build a (test) distribution using Gordon McMillan's
installer (4a3).

I believe I have followed the bundlepmw instructions correctly but the
Builder logic still insists that it use the Pmw module installed in my
Python directory tree.

The documentation says
"Ensure that Builder finds that module and not the development package."

Anyone know how to do that?

(It fails on 'use' reporting unable to find Pmw).

Thanks,
Howard
