Thanks, Nadia, for the offline info. I've got to admit, installing
something as big and dependency-ridden as Python by hand would
probably take things way beyond my level.
I tried installing python25 via fink (BTW, I'm using Tiger, not
Leopard), and then installing the latest ipython, numpy, scipy and
matplotlib using the naive 'python setup.py build; sudo python
setup.py install' method on top of that. Fink tells me that tcltk[|-
dev|-shlibs] 8.4.13-3 are installed.
The good news is that the packages install and import, and after
specifying backend 'TkAgg', pylab.show() opens an X-Window, not an
Aqua window. So that confirms that X11-based libraries are being used
at some level.
The bad news is, it segfaults immediately after the window opens.
I've also tried going the WX and GTK routes under fink's python25,
but always hit a brick wall sooner or later, either in the
installation (wxPython---long, nasty story) or at runtime (fink's
pygtk-py25 installs OK, but at 'import pylab' I get a bunch of gtk
assertion failures followed by a 'Bus Error')
Ah well. Thanks for your help. Given how short life is, I've settled
on the following solution:
import matplotlib
matplotlib.use('Pdf')
import pylab
...
pylab.savefig('/tmp/blah.pdf')
!xpdf /tmp/blah.pdf &
and then keep re-saving (and pressing 'reload' in the xpdf window)
whenever I would normally do pylab.draw(). Some might consider this
a nasty workaround, but I'm used to those---I've used Matlab for years.
