G'day Bill,

Both DB_File and SDBM_File are builtin modules that ship with Perl.

I don't have your Perl/OS combination so I can't really comment on the PPM repository; however, if builtin modules are not normally available via PPM, that would at least explain the absence of DB_File and SDBM_File.

That would also shed some light on your later comment: "I have found SDBM_File.pm in @INC. I do not know how it got there".
