This is a bad idea. Either install Convert::ASN1 using PPM, or install
Strawberry Perl instead of ActivePerl and use CPAN.

That code is just an example. You're not meant to run it directly,
you're meant to read it, understand it, and learn from it. In
particular, it uses variables like $sock and $fh without setting them
up: the implication is that $sock should be a socket handle, but you
have to make that happen yourself.
