You'll find more information in config.log, or you can try it yourself: make a simple test.c with something like int main(void) { return 0; } and try compiling it verbosely: gcc -v test.c My best guess is that you're missing the Sun tools package SUNWtoo (an error like "could not execute as") or maybe SUNWarc instead (a linker error against a non-GCC library). You'll find a list of packages you need in the target-specific install notes, http://gcc.gnu.org/install/specific.html#x-x-solaris2 Rup.
