Current UC2 requires 32 bit runtime compatibility libraries when running
on 64 bit Linux systems. This should be documented in the Release Notes.
Here are some specifics:
Ubuntu 64 bit:
You must install the 'ia32-libs' package
Red Hat 64 bit
Details are still TBD.
And we have an issue with Ubuntu 8.04 (both 32 bit and 64 bit).
See issue 159 for details.
