[igraph] problem installing igraph python version

[Simone Gabbriellini]

Hi List,

hi Tamas,

I have this error when I try to import igraph after installing it with  
python_igraph-0-2.5.1-py2.5-macosx10.5.dmg

>>> import igraph

Traceback (most recent call last):
  File "<pyshell#2>", line 1, in <module>
    import igraph
  File "/Library/Python/2.5/site-packages/igraph/__init__.py", line  
30, in <module>
    from core import *
ImportError: dlopen(/Library/Frameworks/Python.framework/Versions/ 
2.5.2001/lib/python2.5/site-packages/igraph/core.so, 2): Symbol not  
found: _igraph_isomorphic
  Referenced from: /Library/Frameworks/Python.framework/Versions/ 
2.5.2001/lib/python2.5/site-packages/igraph/core.so
  Expected in: dynamic lookup

I am on a PPC Mac OsX Leopard 10.5.4 with developer tools installed.

thank you,
Simone
