Well, the error message you are seeing is characteristic to the case when there 
is a version mismatch between the core igraph library and the Python interface. 
(E.g., the Python interface may correspond to 0.5.3 while the C core that is 
picked up by the Python module corresponds to 0.6). You may try the following:

LD_DEBUG=libs python -m igraph

This will instruct the dynamic to print some debug information on the standard 
error that tells you where it looks for specific libraries. You have to make 
sure that both core.so (the Python interface) and libigraph.so.* (the C core) 
is picked up from the right directory. If you need even more detail, you can 
also try LD_DEBUG=all, but be warned, the latter output is HUGE as it lists the 
bindings for every single symbol in the symbol table.

Anyway, make sure that you don't have an older igraph library lying around on 
your computer that might be picked up by the linker before the one in your home 
directory.
