[BioPython] Having some issue with unicode and Bio.PDB

[WONG Hua]

After your mail, I cleaned up my pythons and re-builded every modules using python 2.4.

Now, instead of the previous error, it gives me:
###############################################################
Traceback (most recent call last):
  File "exportPDBv1_0.py", line 6, in ?
  File "/users2/invites/wong/apps/lib/python2.4/site-packages/Bio/PDB/__init__.py", line 22, in ?
    from Polypeptide import PPBuilder, CaPPBuilder, is_aa, standard_aa_names
  File "/users2/invites/wong/apps/lib/python2.4/site-packages/Bio/PDB/Polypeptide.py", line 5, in ?
    from Bio.Seq import Seq
  File "/users2/invites/wong/apps/lib/python2.4/site-packages/Bio/Seq.py", line1, in ?
    import string, array
ImportError: /users2/invites/wong/apps/lib/python2.4/lib-dynload/array.so: undefined symbol: _PyArg_NoKeywords

It does this when I import Bio.PDB. Not when I import Bio only.
