 I ran into the linker errors described in Boost ticket 4594:
 https://svn.boost.org/trac/boost/ticket/4594

 I decided to try Boost 1.47, and have updated the Portfile.  However, as
 noted in the boost ticket, although 1.47 addresses some of the linker
 visibility issues, it does not solve all of them, notably those in
 thread/exceptions.hpp.  I have added a patch file to the port to address
 this (and also submitted the patch upstream to boost on that ticket).
