I think there is a bug in that package:
the NDBM_File.pm (and following files) are missing in the
binary RPM, looks
like the configure didn't found "ndbm.h".
I have verified that this was included in 5.2 but is not included in
the 6.0 package of perl. I have assigned this to a developer for
NDBM_File functionality is identical to DB_File (the bianry formats of
the databases are compatible)
however, the perl-5.00503-4 from rawhide should fix this.
