I look forward to the unification, but unfortunately I don't think it
will help with this crash (unless the very fact that the numarray and/or
Numeric are installed but not loaded can cause problems).
I see the crash even with this trivial script:
$ python
>>> from pylab import *
>>> plot([1,2,3,4])
>>> show()
boom!
matplotlib 0.87.5 crashes with ~/.matplotlib/matplotlibrc set to use
numarray (1.5.1), Numeric or numpy (1.0b5).

Fair enough. I installed wxPython (2.6) and the above scripts works fine
(as long as interactive is false).

I can try this if you think it will help. It appears to be a lot more
work than just slapping up a plot using pylab so I've not tried it yet.
I also failed to build matplotlib from source. I had all the
prerequisites in /usr/local (and I reinstalled freetype 2.2.1 to be
sure, since the version shown in /usr/local/lib has no resemblance to
the source version). During the build I see these warnings (but no
errors):
/usr/bin/ld: for architecture i386
/usr/bin/ld: warning /usr/local/lib/libpng.dylib cputype (18,
architecture ppc) does not match cputype (7) for specified -arch flag:
i386 (file not loaded)
and after installation, importation of pylab fails as follows:
>>> from pylab import *
