RE: [Boost-Users] Incompatibilities between Date_Time/PosixTime and Boost.Python !?!?!?

This is probably an issue with the date_time configuration.
Try changing the compile macros in boost/date_time/compiler_config.hpp
so BOOST_NO_LONG_LONG_ABS is undefined.  This is the relevant
section of code:

//Work around compilers that don't have std::abs
#if (defined(__GNUC__) && (__GNUC__ <= 3)) || (defined(BOOST_MSVC) && _MSC_VER <= 1200) || (defined(__BORLANDC__) && (__BORLANDC__
>= 0x561))
#  define BOOST_NO_LONG_LONG_ABS
#endif

Maybe STLPort is defining std::abs for 64 bit integers...
