Also, do you need a tester for OS X? I am running 10.4.11 Intel and would be
happy to try and setup some sort of script to download and test regularly.

I'll have to leave the testing question to Troy, who is our testing
guru. If you'd like to test out a binary installer for 10.4 (Tiger),
I'd be happy to go build one for you.

I tried the 1.36 installer for Leopard and had a couple of comments:

1) there is no way to choose an install directory other than /usr/include:/usr/lib - not a big deal, but I spent a while looking in /usr/local first (the Boost default location)
2) the important info notice is for 1.34
3) in code using Boost.Filesystem, linking libboost_system-gcc40-1_36.a and libboost_filesystem-gcc40-1_36.a I get the following linker error:

Undefined symbols:
  "boost::system::error_code::message() const", referenced from:
      boost::system::system_error::what() constin main_mpi.o
      boost::filesystem::basic_filesystem_error<boost::filesystem::basic_path<std::basic_string<char, std::char_traits<char>, std::allocator<char> >, boost::filesystem::path_traits> >::what() constin main_mpi.o
ld: symbol(s) not found

I haven't tried using the dylibs yet to see if that solves the problem, but it's a little strange...
