FreeBSD 10 uses clang instead of gcc. After the usual ./prebuild.sh,
../configure, etc.

Seeing if this will solve the issue.

That worked. Needed to change every instance of "shared_ptr" to
"boost::shared_ptr"

d'oh! Looks like the binary is slower than the one compiled with gcc (slower by
about 10 seconds on the benchmark scene, clang 3.3 {freebsd 10.0} vs. gcc 4.2.1
{freebsd 9.2}). Oh well.

From measurement on linux, gcc 4.7 / clang 3.3 (4.2.1), it depends on
the availability of HT.
gcc is better with HT, clang is better without. And icpc (intel
compiler) wins everytime.

Well, now this is interesting. Working on renders containing sslt, focal blur,
and radiosity. The clang compiled binary is 10 minutes faster than the gcc
compiled one (CPU: Phenom II x6 1090T; 2 hours 4 minutes for clang; 2 hours 15
minutes for gcc).
