OK, great -- thanks for th info.  From reading David's comments in the
earlier thread:

still works.
  David > numpy 1.3.0 is backward compatible with 1.2.1

it looks like our best bet will be to build our python2.4 and
python2.5 binaries against 1.2.1 and our python2.6 binaries against
1.3.0 (since there are no older python2.6 numpy builds on the sf site
anyhow).  I'll post on the mpl list and site that anyone using the new
mpl installers needs to be on numpy 1.2.1 or later.
