At least, App::ipchgmon 1.0.2 has entered your CPAN directory. This means that anything you want to upload must have a new (higher) version number.

I can't make sense of the missing Module::Pluggable prerequisite, as that is listed indirectly through your prerequisites, and even less of the DateTime prerequisite, as you list that one directly.

You also have a NAME section in your POD, but your package name in App/ipchgmon.pm is:

package ipchgmon;
[download]

I think that CPAN / MetaCPAN expect App::ipchgmon there - that may be the cause.
