Below is the context of a post I made elsewhere regarding pysol. Your problems may be due to what I say towards the end regarding possible dependencies on the freerock gnome libs. You appear to have done just what I did. The only difference may be freerock gnome.
I have PySol running on Slackware 10.2 with Freerock Gnome installed.
The PySol Package was from here:
http://www.spykes.net/packages/pysol-4.82-i486-1spi.tgz
(mentioned in another thread)
There was a dependency on smpeg which I got from here:
http://www.linuxpackages.net/pkg_details.php?id=7638
There was a package of smpeg for 10.1 as well. The 10.2 package was built
on an install with the freerock libs. I don't know about how the 10.1
package was built. I'm running python version 2.4.1
