I have some _suggestions_ (only) if you're still game...

I wonder if you should tell Pari to use the version of GMP installed  
in /opt/local [by MacPorts] (rather than usr/local where it appears  
you have another GMP installation, possibly outdated). Maybe "./ 
Configure --with-gmp=/opt/local" or such...

I have successfully used this procedure (immediately above) to compile  
GMP on OSX Leopard Intel 10.5.8 [like you] - however the version of  
GMP I used (only) was 5.0.1

don't actually know what that one means - maybe someone else will...
