Here is a 1 minute review of your project perlmod.

• reusing perlmod name
• no requirements list,
• no Makefile.PL
• no pod
• no strict,
• no test suite
• hand parsing of switches
• raw shell escapes
• code like

  if($install_module ne ""){
      &installModule($install_module);
      return 0;
  }

• no support for Module::Build
• not an improvement over cpan or cpanp
• no user base
• single developer
• marketing alpha quality code in a tutorial thread as 1st post

I hope you have enjoyed writing this program, but no thanks, sorry.
