The Boost C++ library is installed. Current version is 1.35.0.
To use it with a header-only library, you simply need to add /usr/local/include to your include path.
The bjam executable is available in /usr/local/bin.
Binary libraries have been built using the Sun toolset and placed in /usr/local/lib. These have been built as 64-bit, using the Sun STLport standard c++ library.
All of the boost libraries are available with the exception of python, graph, and mpi. Also regex is built without ICU. It's basically the minimal-dependencies option.
Here's the build command I used:
$ make BJAM_CONFIG="stdlib=sun-stlport address-model=64"
