"I'm guessing we need a couple utilities at the perl infrastructure level: One to "fork" a cpan dist in to github (for dists that aren't on github, but L4P already is), and then an update to cpan/cpanm to get it to prefer where to get a specific dist from."

First, create the repository on your Github. I created one called simply "log4perl", then:

cpan -g Log::Log4perl
tar -xzvf Log-Log4perl-1.49.tar.gz
cd Log-Log4perl-1.49
git init
git add .
git remote add origin https://stevieb9@github.com/stevieb9/log4perl.gi
+t
git push -u origin master
[download]

Now you've make a fork of the 1.49 version of the distribution on your own Github.

Now, when you want to install with cpanm:

cd c:\users\steveb\repos
git clone https://github.com/stevieb9/log4perl
cd log4perl
cpanm .
[download]

Or, do a make dist in your repository, add the newly created tarball into the repo and do a push, then:

cpanm https://github.com/stevieb9/log4perl/blob/master/Log4Perl-1.53.t
+ar.gz
[download]

See also gitpan, in this case https://github.com/gitpan/Log-Log4perl.

First, create the repository on your Github.

Actually, the thing I needed to do first was to create a repos directory on my local machine, and then within it run:

cpan -g Log::Log4perl
tar -xzvf Log-Log4perl-1.49.tar.gz
cd Log-Log4perl-1.49
git init
git add .
git remote add origin https://github.com/TBlazer66/log4perl.git 
git push -u origin master
cpanm . --force
[download]

I was very happy to see such quality responses to my question. Thank you. Perl is such a good activity for Xmas eve.
