IRQ client?

Can anyone recommend an IRQ client that works under
Linux? I just started a Perl programming job for a
company in Oregon, and will be exected to stay in touch
using IRQ.

Freshmeat shows a bewildering array of choices. (82
hits on IRQ.) I don't have time to try fifty that don't
work before finding one that does. I need it
immediately. (If not sooner!) Thanks for any
suggestions.
