Sorry to post again :) I'm trying to compile graph-tool on my new desktop. I've downloaded the development source code and I think (or thought!) I have everything needed for the install. Here's what I do logged in as root: $./autogen.sh $./configure --disable-visibility $make $make install All seems to work with no visible errors. However, here's what I get when I type $graph-tool --help Traceback (most recent call last): File "/usr/local/bin/graph-tool", line 19, in <module> from graph_tool import * File "/usr/local/lib/python2.5/site-packages/graph_tool.py", line 26, in <module> import libgraph_tool ImportError: No module named libgraph_tool I must be making a basic mistake somewhere? I've got python 2.5.1 on an ubuntu 7.10. Many thanks again, Rui
