Built bjam by:

        ./build.sh <other-options> debug

then, run the above commnad under debugger. When using gdb, that's:

        gdb --args ./tools/jam/src/bin.aixppc/bjam --toolset=vacpp install
        (gdb) run

but I have no idea what's debugger is on AIX. When it segfaults,
get and post a backtrace, or maybe even poke at the code to see what's wrong.
But actually, 'install' is 'stage' + installing headers, so you might want
to get 'stage' to work first.

Ouch! If compiler hangs compiling Boost, it seems like compiler bug. In fact,
that particular file is expected to take a long to compile, so maybe you did
not wait long enough?
