Verify that perl is installed on your OS. If you don't know
what perl is, go to the perl site
and learn this wonderful language.
I don't have any time to explain how perl works, sorry.
To get perl follow this
link.
If you want to use the M1->M2 converter or the M2 import/export
scripts, you must have perl 5.8.0 or later installed. You
can verify this by launching perl -v on a shell:
> perl -v
This is perl, v5.8.7 built for i386-freebsd-64int
(with 1 registered patch, see perl -V for more detail)
