... freeing them from the shackles ...
You have no concept of how corporates work. They love shackles. They invent shackles were there are none.
Do a supersearch of this place and look for all the posts that say variations on the theme of "I'm not allowed to install any modules" or "getting approval for the installation of a new module is a long and tiresome process".
If an IT department is going to distribute a Perl-based application to a couple of hundred user machines, the last thing they want to do is distribute a compiler, and mock-unix development platform to every machine also. Nor do they want to have to visit each machine individually and answer the same bunch of questions over and over in order to perform the installation.
And they sure as hell don't want to enable the user to pull random chunks of sourcecode from an open server (CPAN) and compile them locally.
They are just packaged installers.
Your concept of an 'installer' is bad also. When a corporate uses an MSI installation, it gets much more than just a bunch of files slapped onto the disk somewhere and then replicated to another part of disk leaving all the junk lying around.
A few of the benefits of using an MSI installation:
And this doesn't even to begin to list all the security aspects. Like installing Perl on a machine such that only users who are members of a particular group can use it, in hot-desk environments where any employee can sit down at any machine and log on, but each user has different priviledges. Using an MSI, installing an application so that an non-authorised user won't even be able to see it is trivial.
Remote installs. I built a system for the remote installation and maintanence of application software on 40,000 desktops and portables located in dozens of separate sites distributed across an entire country. Any employee could walk into any site, sit at any desk and log on and his user profile (down to his choice of fonts and desktop colours--which is a legal requirement for visually impaired employees) was loaded onto the machine automatically. And if he attempted to use an application that had never been installed on that particular machine before, it was installed for him as he waited. When he logged off and the next user sat down to use it, it was a legal requirement that the next user would never be able to see anything that the previous user had been doing. There are 23 divisions within the company (actually a government department), and it is a legal requirement that all their work must be kept separate.
Using MSIs in this type of environment is a delight, because it knows and understands about the security setup; roaming profiles; domain based networking; and all the other bits and pieces that are need to make this work.
Trying to set this up with a 'installer', based around an emulation of an OS that has none of these concepts, would simply be impossible.
