sccom not found

Hello,

I have the Modelsim SE 6.5b installed. It works fine with Verilog, SystemVerilog, VHDL, etc., but it doesn't work with SystemC. The returned message is:

**

couldn't execute "/opt/altera9.1/modelsim_ase/linux/sccom": no such file or directory

**

But I can find this binary file in the "bin" folder! So, I made a symbolic link in the linux directory, but it did not work again.

Could someone say me what I'm doing wrong?

Thanks.
