We've tried running the "linux32" shell to fake it into thinking it's fully 32-bit instead of 64-bit, etc... No luck so far. I'd have guessed that's because 64-bit OS libraries are installed and not always the 32-bit equivalents are (this is on CentOS 5.3 BTW). But FGS appears to be built static, so that shouldn't matter right?

Wendell,

I don't think it'll work because all FGS libraries are built in 32 
bits.  Your best option now is to download the FGS VM 9.5 from here:

 http://dev5.mapgears.com/debian-40r0-i386-netinst-fgs-9.5.tgz

and compiled all packages on your 64 bits.
