Would the people who have these problems be so kind to try out the
following (yes *unofficial*) patch to configure and Python/import.c?
It adds a test for the dlopen() function and turns on use of shared
libraries only if that exists as well. Let me know if it works!
(A quicker work-around would be to simply #undef HAVE_DLFNC_H in
config.h.)
