Ah, if I remember correctly you only get a "libboost_regex.*" if you invoke 
bjam with --layout-system: this is primarily intended for system 
integrators.  I've no idea why you got linker errors from the above 
binaries, you should be able to use -lboost_regex-gcc34 as a linker option 
and have it just work.
