Make sure the same database libraries are available on the two platforms.
Apparently, gdbm isn't available on your Solaris system. Shelve uses
anydbm, which runs through a canned list of potential modules. It uses the
first one it finds. It might be possible to also fiddle the order of the
anydbm._names list to guarantee whatever you have in common on the two
platforms is found first.
