[igraph] ubuntu python package is broken?

[Dhruv Bansal]

Hello,

I'm running Ubuntu 7.10 and I added

deb http://cneurocvs.rmki.kfki.hu /packages/binary/
deb-src http://cneurocvs.rmki.kfki.hu /packages/source/

to my /etc/apt/sources.list which allowed me to install libigraph,
libigraph-dev, and python-igraph packages using apt-get.

When trying to import the igraph module into the Python interpreter I
get the following error:

>>> import igraph
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.5/site-packages/igraph/__init__.py", line 30, in 
<module>
    from core import *
ImportError: /usr/lib/python2.5/site-packages/igraph/core.so: undefined symbol: 
igraph_authority_score

I can write a C program and compile it against the igraph library from
the packages like so

g++ -ligraph -I/usr/lib/igraph my_igraph_program.c

without any errors and compilation and execution for the C program are
identical to when I compile against (an older) source version

g++ -ligraph -I/usr/local/lib/igraph my_igraph_program.c

where I'd previously installed version 0.4.5 of igraph into
/usr/local.  (I was also able to build the Python wrapper against this
older version of the source.)

This seems to be a problem with the Python wrapper and not the actual
C library.  Has anyone else had similar problems?

Thanks!
