A full Ruby distribution is about one-third of the size of a base Perl
distribution, and yet includes a lot of stuff missing from base Perl (such
as openssl libraries)

Now, I can't give you an exact answer to your question. If you look at
ext/Setup you'll see a bunch of 'optional' C libraries you can disable or
enable. You can leave them all disabled of course, but things like 'socket'
would be important for network clients.

However, most of the libraries supplied with Ruby are written in Ruby.
You'll have to look at the sizes of them and decide which you want to leave
out. If you don't want an XML parser, then you can leave out REXML (but then
again, Jabber is an XML-based protocol I believe).

Brian.
