worth to give it a try and send me more specific output. You should

+=head2 CD-ROM support
+
+The C<urllist> parameter of the configuration table contains a list of
+URLs that are to be used for downloading. If the list contains any
+C<file> URLs, CPAN always tries to get files from there first. This
+feature is disabled for index files. So the recommendation for the
+owner of a CD-ROM with CPAN contents is: include your local, possibly
+outdated CD-ROM as a C<file> URL at the end of urllist, e.g.
+
+ o conf urllist push file://localhost/CDROM/CPAN
+
+CPAN.pm will then fetch the index files from one of the CPAN sites
+that come at the beginning of urllist. It will later check for each
+module if there is a local copy of the most recent version.
