You'll either have to get the admin to install it, or you'll need some sort of shell access. If neither of those are available, you're out of luck.

Not sure if your definition of 'shell access' extends beyond an interactive session with telnet or ssh, but in many cases, all you really need is the ability to execute arbitrary scripts on the target machine ... something you probably already have in the form of CGI!

#!/bin/sh

echo "Content-Type: text/plain"
echo ""

(
  gzip -cd Module-2.1.tar.gz | tar xvf -

  cd Module-2.1 

  perl Makefile.PL LIB=~/lib

  make
  && make test
  && make install
) 2>&1

Sure it can be a pain, but it works.
