Is there a quick way to tell, for a given installation of Perl, what the default DBM version is? In other words, what am I getting if I don't specify "use SDBM_File;" or one of its ilk? My reason for asking is that my hosting service and my home mirror now have two different versions of Perl (5.005 vs. 5.8) and they produce different kinds of files with dbmopen. So I now need to specify a DBM module in my scripts (same on both systems) so both will generate and use the same format that my hosting service uses as a default.
