Hi,

we're running Matplotlib 1.0.0 with Python 2.6.2 on CentOS 5.6.  When 
importing from matplotlib._path, users get an error message

"undefined symbol: 
_ZSt16__ostream_insertIcSt11char_traitsIcEERSt13basic_ostreamIT_T0_ES6_PKS3_l"


I'm at a loss.  There were no errors during the installation

Generating the error:

$ python-2.6
Python 2.6.2 (r262:71600, Aug  5 2010, 14:21:11)
[GCC 4.4.4] on linux2
Type "help", "copyright", "credits" or "license" for more information.
 >>> from matplotlib._path import affine_transform
Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
ImportError: 
/g/software/linux/pack/python-2.6/lib/python2.6/site-packages/matplotlib/_path.so:
 
undefined symbol: 
_ZSt16__ostream_insertIcSt11char_traitsIcEERSt13basic_ostreamIT_T0_ES6_PKS3_l
 >>> exit()
$

Anyone has seen this before and/or knows a fix?  There are some reports 
about such an error on the web, but they are all quite old and I cannot 
relate them to the current issue.

Thanks in advance

     frank
