[Pythonmac-SIG] pythonmac packages question

Thanks folks....the saga continues...

I've gotten easy-install running, which allowed me to download a  
brand-spanking new version of ipython (0.7.2). Recall I've also  
installed (via http://pythonmac.org/packages/py24-fat/index.html)  
matplotlib, Numeric, and wxPython (the latest version: 2.7.1.3; there  
was also a 2.6.3.3 version).

I run my new ipython with the -pylab option (using WXAgg backend and  
interactive True) and still get the following warning:
---------
/Library/Frameworks/Python.framework/Versions/2.4/lib/python2.4/site- 
packages/ipython-0.7.2-py2.4.egg/IPython/Shell.py:709:  
DeprecationWarning: The wxPython compatibility package is no longer  
automatically generated or activly maintained.  Please switch to the  
wx package as soon as possible.
   import wxPython.wx as wx
----------

followed by the same ability to not be able to use matplotlib  
commands, e.g.

     from pylab import *
     plot([1,2,3])

gives the same Memory / wx error:
-------
In [3]:
exceptions.MemoryError                               Traceback (most  
recent call last)

    1047         # Render to the bitmap
-> 1048         self.draw(repaint=False)
    1049         # Update the display using a PaintDC
    1050         self.gui_repaint(drawDC=wx.PaintDC(self))

      65             self.gui_repaint()
MemoryError: _wxagg.convert_agg_to_wx_bitmap(): could not create the  
wx.Bitmap
--------

I also tried using the TkAgg backend, which produces very different  
complaints, e.g:
----------------
In [16]: rcParamsDefault['backend']
Out[16]: 'TkAgg'
<snip>
In [18]: plot([1,2,3])
<snip>
exceptions.TypeError                                 Traceback (most  
recent call last)
<snip>
/Library/Frameworks/Python.framework/Versions/2.4/lib/python2.4/site- 
packages/matplotlib/axes.py in set_xlim(self, xmin, xmax, emit)
    1225             xmax += 1e-38
    1226
-> 1227         self.viewLim.intervalx().set_bounds(xmin, xmax)
    1228         if emit: self._send_xlim_event()
    1229         return xmin, xmax
<snip>
TypeError: only length-1 arrays can be converted to Python scalars.
-----------------

Have any of you been able to use matplotlib w/ipython in the MacPorts  
setting? What am I doing incorrectly?

Thanks again,
