DLL load failed

Hi,
Having problem running agilo using matplotlib :

File "d:\agilo\python25\lib\site-packages\matplotlib-0.98.5.2-py2.5-win32.egg\matplotlib\transforms.py", line 34, in <module>

from matplotlib._path import affine_transform
ImportError: DLL load failed: The specified module could not be found.

Any would be appreciated,
Best regards,
Thomas
