[boost] program-options thread problem

I have both added current program-options to my boost build tree, and all
the usual variants of libboost_program_options-gcc.a, also
libboost_python-gcc-mt.a.

Linking against libboost_program_options-gcc.a I get errors about pthread
symbols.  Adding -pthread fixes it.  It looks to me that
libboost_program_options-gcc.a 
is referencing pthread symbols.

nm /usr/local/src/boost_1_31_0.gcc34/stage/lib/libboost_program_options-gcc.a
| grep thread
         U pthread_mutex_destroy
         U pthread_mutex_init
         w pthread_mutex_lock
         w pthread_mutex_unlock
         w pthread_mutex_lock
         w pthread_mutex_unlock

Yup,sure is.
