Right.  It all seems perfectly clear after the fact, but it was pretty
confusing at the time.  I was already kind-of aware of the ABI/ISA
issues, but not prepared for the obscureness of the error messages
when I did things incorrectly.  Paying close attention to the log I'd
kept when building GMP, and running a few "ld -Dlibs,detail ...",
finally got me pointed the right direction.

I'd HOPE that a 64-bit version is faster!  (And, I'll be curious to
see.)

Thanks again for your help.
