Re: [igraph] Problem importing igraph in Python 2.5 (Mac OS 10.6) Cannot recognize _igraph_vector_destroy

[Tamas Nepusz]

Hi Michael,

One more thing: if you tried to install igraph by some other means before
using the installer, then please remove all instances of libigraph.dylib
from your hard drive before running the installer. You can find them by
running "find / -name libigraph.dylib" from the command line. (This is to
avoid cases when the dynamic linker picks up some other version of
libigraph.dylib and not the one provided by the .dmg installer).

Cheers,
T.
