ModleSim Not Working With Linux Mint 14

Hello,

I've installed the 4.4GB file for the free web edition of Quartus II and ModelSim in Linux Mint Nadia 14, KDE edition. Quartus II works without a problem, but every time I try to use the RTL or Gate Level Simulation buttons, I get the following message:

--- Quote Start ---

Error: Error: Can't launch ModelSim-Altera Simulation software -- make sure the software is properly installed and the environment variable LM_LICENSE_FILE or MGLS_LICENSE_FILE points to the correct license file.

Error: Error: NativeLink simulation flow was NOT successful

--- Quote End ---

I've gone through the website to get the free license file (which I thought was not required) and I've set the LM_LICENSE_FILE environment variable to point to it.

Nothing seems to work. Any help would be greatly appreciated.

Thanks!

EDIT1: if I run vsim directly from the command line, I get the following error:

--- Quote Start ---

/altera/13.0/modelsim_ase/bin/../linux/vish: error while loading shared libraries: libXft.so.2: cannot open shared object file: No such file or directory

--- Quote End ---

EDIT2: I duel boot Linux Mint 14 and Ubuntu 13.04. I installed the package with Ubuntu and had no problems starting ModelSim. Strange.
