Need to include a check for perl modules to be installed

[pashadag]

(from Rayan)

`perl cnfind.pl` crashes with: "Can't locate File/HomeDir.pm in @INC .."

Need to install File::HomeDir in Perl.

To do this, type this in a terminal (no root needed):

wget -O- http://cpanmin.us | perl - -l ~/perl5 App::cpanminus local::lib
eval perl -I ~/perl5/lib/perl5 -Mlocal::lib
echo 'eval perl -I ~/perl5/lib/perl5 -Mlocal::lib' >> ~/.bash_profile
cpanm File::HomeDir
restart bash
