Description of problem:
There is no way to use an internal perl mirror with perl cartridges in OSE.
When I checked bug 1012721, I found perl cartridge have the similar problem.

Version-Release number of selected component (if applicable):
puddle:[1.2/2013-10-03.1] 
openshift-origin-cartridge-perl-0.4.8.2-1.el6op.noarch


How reproducible:
always

Steps to Reproduce:
1.create a perl app
#rhc app create perlapp perl
2.configure deplist.txt 
#cd perlapp;echo GD >>deplist.txt
3.git push
#git commit -a -m 'test' && git push


Actual results:
Output:
remote: --> Working on GD
remote: Fetching http://search.cpan.org/CPAN/authors/id/L/LD/LDS/GD-2.50.tar.gz ... OK
remote: Configuring GD-2.50 ... OK
remote: Building GD-2.50 ... OK



# vim /usr/libexec/openshift/cartridges/v2/perl/bin/build
lines19-25

 19 MIRROR="--mirror http://search.cpan.org/CPAN"
 20 
 21 if [[ "$LINUX_DISTRO" =~ $RED_HAT_DISTRO_NAME* && $OPENSHIFT_GEAR_DNS =~ .*\.rhcloud\.com$ ]]
 22 then
 23   MIRROR="--mirror http://mirror1.ops.rhcloud.com/mirror/perl/CPAN/ $MIRROR"
 24 fi

The codes above prove that there is no way to use an internal perl mirror.

Expected results:
Should provide a method to use an internal mirror
We need a similar patch for perl cartridge just like python cartridge (BZ#1012721)
