[Pythonmac-SIG] pythonmac packages question

[belinda thom]

Hi,

As of my prior post, I was able to get into pythonmac.org.

There I found many of the packages it seems I'll need. I was able to  
install Numeric and WxPython (I chose the later dmg, v 2.7.1.3) and  
matplotlib.

This site has no Tkinter and no IPython packages. Where do MacPython  
people go for such things?

Meanwhile...

If I run python alone and try out pylab, I get the following errors:
----------------

     self.viewLim.intervalx().set_bounds(xmin, xmax)
TypeError: only length-1 arrays can be converted to Python scalars.
------------------

I've read elsewhere IPython is the rec'd way to use pylab b/c it sets  
up some needed things like an extra thread. As a temporary hack, I  
added a symlink to /Library/Frameworks/Python.framework/Versions/2.4/ 
lib/python2.4/site-packages that points to the macports IPython  
install I'd done previously. This seems to work (ipython runs).

However, when I do:

The initial warning implies the MacPython stuff isn't happy with  
macport's IPython's.

I'm confused as to how to proceed. Advice greatly appreciated.
