[R] Illegal instruction - R 1.7.1 under RH 9 Intel

[rab]

I installed R 1.7.1 on my intel desktop (RH 9) without any problems.  I 
installed the same binary (R-1.7.1-1.i386.rpm) on my Toshiba Satellite 
2535cds (RH 9). R starts as usual all the way to how to quit then prints:

Illegal instruction

and exits to the shell prompt. I also had installed the patched readline 
rpm.

How can I fix this? I've never had a problem running R before on the laptop.
