matcher extension on MacOSX 10.4 not working

[Ian Tegebo]

As per the rxvtperl manpage, I've put the following in my .Xdefaults:

    URxvt.perl-ext:           default,matcher
    URxvt.urlLauncher:        open
    URxvt.keysym.C-Delete:    perl:matcher
    URxvt.matcher.button:     1
    URxvt.matcher.pattern.1:  \\bwww\\.[\\w-]+\\.[\\w./?&@#-]*[\\w/-]
    URxvt.matcher.pattern.2:  \\B(/\\S+?):(\\d+)(?=:|$)
    URxvt.matcher.launcher.2: gvim +$2 $1

I'm on MacOSX 10.4 and have installed MacPorts and then subsequently
installed urxvt.  I've set the urlLauncher to 'open' and have confirmed that
from the CLI, 'open http://www.google.com' works as expected.

I then used 'xev' to confirm that the button press was being mapped to '1'.

At this point, I'm not sure how to proceed.  Can anyone point me in the
direction of exposing urxvt's processing of mouse button presses?  Does
this sound like a reasonable next step?

BTW, I have successfully gotten this setup working on my Ubuntu box.

Thanks,
