At the risk of being repetitive (with respect to the previous answers)... you don't need to chroot for that :) Jokes apart, have you considered to use a Live CD distro, like Knoppix? This shouldn't spoil anything (hopefully).

I once compiled Perl 5.8.6 in a chrooted environment, that of Linux From Scratch - try to see there if there's something that can help you. In your particular case, try to

   prompt$ ldd miniperl
[download]

and try to see if it requires some lib that's not included in your chroot environment.
