You need to look at i386-apple-darwin10.7.0/x86_64/libgcc/config.log. That should show the reason why you got that error. There's usually a lot of information in there; look for the above error message. It should show the program that it tried to compile and the error message it got when it failed. A pretty common cause for this is that you built gmp, mpc, and mpfr without using --disable-shared, and you haven't told the dynamic linker where to find the shared libraries. Ian
