This certainly is not the output of the makefile that is
provided in the boost/libs/python/build directory. The
ld commands fails to link against all the support *.o,
or alternatively the libboost_python.a file.

I have successfully built Boost.Python with linux_gcc.mak
under RH 7.1 with the gcc 2.96 compiler. However, the tests
fail at runtime b/o the notorious exception handling bugs.
Next I have tried gcc 2.95.3. Same problem (which is interesting,
because gcc 2.95.3 works under RH 6.1). The only compiler
that works both at compile-time and at runtime under RH 7.1 is
gcc 3.0 (you can ignore the long list of bogus warnings when
compiling some of the richcmp?.cpp tests).
