Alloc error

I recently upgraded to the latest version of matplotlib using the
ScipySuperpack. However it seems that pylab is not playing nice

with Tcl/Tkinter, creating an alloc problem. I am using ActiveTcl

8.5.00 and TclTkAquaBI-

The error is shown below:

A google search came up empty, except that this might be a Tcl

problem because threading was not enabled, but the ActiveTcl

should have that enabled. The problem showed up when I

upgraded to the new version of matplotlib, so I am wondering

if it is the culprit of the error. Any help is appreciated.
