Lately I've been having sub-optimal results using the cpan shell on my laptop. The problem is all up front: the inability of cpan to quickly access files on the mirror. The following now typically takes a full 3 to 5 minutes:

$ cpan
CPAN: File::HomeDir loaded ok (v0.58)
CPAN: Term::ANSIColor loaded ok (v1.12)
Sorry, we have to rerun the configuration dialog for CPAN.pm due to
some missing parameters...

Normally CPAN.pm keeps config variables in memory and changes need to
be saved in a separate 'o conf commit' command to make them permanent
between sessions. If you set the 'auto_commit' option to true, changes
to a config variable are always automatically committed to disk.

 <auto_commit>
Always commit changes to config variables to disk? [no] 



Please remember to call 'o conf commit' to make the config permanent!

I know that long ago I had that msu.edu server in my list, but I definitely recall removing it. But I can't seem to get rid of it, and all the failures are associated with that mirror.

Can anyone diagnose?

Thanks in advance.
