I can't help much in that case because I don't use graphical package managers like Synaptic.
Is the package installed but with an error, or is it not installed whatsoever?
And what is the exact name of the package?
I would try to do this in the command line:
sudo apt-get remove package-name
sudo apt-get install package-name
If you still get the error, I guess the only option would be to compile it from the source tarball.
