Did you try without the --with-boost-thread=boost_thread-mt ?

Did you install the libboost-thread1.49-dev package ?

Looks, -pthread is ok. (whereas -lpthreads is not :-), be happy of the
gnu compiler )

Well, that portion of config.log is irrelevant, it checked -lpthreads
and we know the result.

pthread was checked as ok, the issue is with the boost-thread library.

Yep, attachment are not allowed in this group.
IIRC, you might need LIBS="-lboost_system" on the configure line to have
the boost_thread-mt usable.
Do not ask why.
