A Marpa mailing list
Ruslan Zakirov has started a Google mailing list for discussions about Marpa: marpa-parser@googlegroups.com -- I am grateful to Ruslan for doing this and plan to follow the mailing list.
On another topic, I will be removing the "bare name" version of Marpa from CPAN shortly. The "bare name" Marpa is a legacy, deprecated version and is simply causing too much confusion, with search engines and elsewhere. The official, stable version of Marpa remains Marpa::XS.

@Alberto: GLib seems to be on CPAN: http://search.cpan.org/dist/Glib/
And my cpanm finds it
