[PlanetCCRMA] New install - FC5/SMP - Ardour fails w/"illegal instruction"

[James P. Early]

Greetings,
  I successfully completed a FC5/PlanetCCRMA installation/upgrade according to
the posted instructions. I then used yum to install Ardour. I next tried to run
Ardour, but it consistently fails to load with the following error:

[earlyjp@localhost ~]$ ardour

Illegal instruction

I've tried using the SMP version of both the DESKTOP and REALTIME kernels, as
well as launching Ardour as both a user and root. All produce the same result.

I found one mention of this error in the PlanetCCRMA achive, but it is unclear
if a solution was ever found. Then, I found a mention of the error on the Ardour
forum:

http://ardour.org/node/159

In it, Paul Davis mentions that the error can occur when the package is built
using SSE instructions. My system is a dual PII/400, and a cat /proc/cpuinfo
does not indicate an SSE flag. Does this mean that I must compile Ardour rather
than using the CCRMA package?

Thanks,
Jim
