My guess is that the build-process was screwed by some improper
reconfiguration.  Observe that the symbol `__gmpn_add_n' should have been
provided by GMP, but there is no -lgmp on the compiler command line.  The
other missing symbols are probably explained also by some mishap while
reconfiguring.  Please delete everything, unpack again, configure, make,
make check, make install in that order.  Does this help?

Please set optimization to `-O', `-O1', `-O2' or maybe `-O2 
-fno-exceptions' but *never* to `-O0' or `-O3' while compiling the library
proper.  The latter two do not work with the automatic module ordering
scheme.  Though it appears that you set `-O', which should be okay.

Regards
    -richy.
