You need to build Boost with GCC 3.4, otherwise your program and Boost
will be trying to use different definitions of the stdlib components.

Since you seem to be using a version of Boost installed in /usr/lib, was
it a binary installation from RPM or something?

If so, you'll need to get a new version of that binary package that was
built with GCC 3.4, or build your own copy of Boost with GCC 3.4, install
it somewhere else and link to that version.
