Note that it used the system compiler, Apple's GCC 4.0.1, and not anything from MacPorts for the first compiler phase.) It didn't build all the way through; here's the last few lines: //--- checking for gawk... awk checking whether make sets $(MAKE)... yes checking for --enable-version-specific-runtime-libs... no checking for style of include used by make...

If you meant to cross compile, use `--host'. See `config.log' for more details. make[1]: *** [configure-target-libquadmath] Error 1 make: *** [all] Error 2 [daryle:gcc-obj]$ l //--- It seems that it tried to build "libquadmath" thinking all PowerPC systems are 64-bit, while mine is 32-bit. I didn't reach the error I reported with MacPorts' build yet. Is there any way to force libquadmath to compile in 32-bit mode? (If that's impossible, is it skippable?) I'll try to attach the "config.log" file. I'll retry make when you guys let me know how to fix up libquadmath.
