Well, I too hat lots of problems with Solaris. Personally I think that  
adding GMP and MPFR as hard requirement was a mistake. But there you  
are. Anyway - in the the following statement set before compiling GMP  
and MPFR myself sorted my troubles:

typeset -x ABI="32"

Note that I use Z-Shell - if you use another shell you might need to  
use "declare -x" or "export".
