Finally got LLVM-GCC-4.2-2.5¹ to install on the computer at work. It took 2 near solid days of compiling to get right but should hopefully be worth it. Up until now we've been stuck with GCC 3.4.6, which is not only rather old, but also buggy in such a way that it couldn't compile LLVM—I had to install GCC 4.2 first to do the job. I'm excited though; I updated Apple's Dev tools on my laptop along with the upgrade to OS 10.6, and discovered that Radiane runs literally twice as fast when compiled by LLVM as when compiled by GCC. I wish Clang were ready for C++, but this is already a stupendous step forward.
