[SciPy-user] matplotlib on osx

[John Lichtenstein]

Has anyone gotten matplotlib running on OSX recently? I tried  
upgrading to 10.4.8, and building Python 2.5, numpy, scipy, libpng,  
and freetype from source. Everything went fine, even matplotlib  
installed without an error. But when I import matplotlib I get

21:49:24: Debug: ../src/common/object.cpp(224): assert "sm_classTable- 
 >Get(m_className) == NULL" failed: class already in RTTI table -  
have you used IMPLEMENT_DYNAMIC_CLASS() twice (may be by linking some  
object module(s) twice)?
../src/common/object.cpp(224): assert "sm_classTable->Get 
(m_className) == NULL" failed: class already in RTTI table - have you  
used IMPLEMENT_DYNAMIC_CLASS() twice (may be by linking some object  
module(s) twice)?
Trace/BPT trap

What's the clean way to uninstall Python? I used to have a working  
matplotlib using the pythonmac distribution. Maybe I can get back to  
that.
