Well, I've just looked into your files.
I can now said that I've made a mistake. You're plugin seems to doesn't
use tex2im now.
But I know what makes me missunderstand :
in README file :
"README:This is a plugin for Gaim [1] that allows you to display LaTeX
[2] output into your IMs. This plugin needs the tex2im tool [3]."

Well, I don't know LaTeX enough to gives you more commands (if there's
any)
