Redhat 8.0 Error

Hello

I downloaded modeller6v2 and 6v1. Both packages run correctly on a SGI (IRIX 6.5), but when I install them on a Redhat linux box I get an error message at the welcome screen that says "Illegal instruction" and then the program exits.

Has anyone else seen this before? Is there a fix?

Thanks for you help!
