[boost] sched_yield symbol not found (SunOS/gcc)

For the last couple of days we are experiencing a problem when using boost cvs
on this platform:

SunOS mcfsrv 5.8 Generic_108528-08 sun4u sparc SUNW,Ultra-Enterprise
gcc 3.0.4

The error message is:

ImportError: ld.so.1: /home/users2/nksauter/python/bin/python: fatal:
relocation error: file ../lib_python/cctbx_boost/uctbx.so: symbol sched_yield:
referenced symbol not found

Context: Python uses dlopen() to import a Boost.Python module.
The exact same source code works under Linux/gcc, Tru64/cxx and
VC++6, among others.

What could be the problem?

Thanks,
        Ralf
