The problem:
I do not have perl in my system and I do not have permissions to install it.

It would be nice if I will be able to install perlbrew into my home directory.

Since perlbrew itself is written in perl, and without rewriting it with sh or something that's basically omni-available, this bootstrap problem cannot be easily mitigated.

But perhaps we could somehow prepare a binary perl distribution that is tailor-made, relocatable, self-contained, targeting at OSes that ship without an perl. Or we could try the approach of shipping perlbrew itself as a PAR-packed app.

But furthermore, perlbrew also requires a set of toolchain (c compiler, sh, .... etc) on the sysetem to build whatever perl's available. At the moment there are no binary installations just yet (perhaps there should be ?) So that's another blocker when we are in the situation when $USER really lacks permissions to install stuff onto the system.
