As Marc Glisse wrote a post later it has something to to do with optimization flag: --no-add-needed which is used on the ubuntu platform. During compile/link time no symbols are used from the boost date_time library by the module itself so the linker does not link the libary at all. Later at runtime i load a bunch of other 'plugins' via apr_dso_load(...). These plugins then need some symbols from boost date time and the trouble begins. All i have to do is to tell the linker to link the libray even if it's symbols are not used in the module at build time.
