help // ardour on mac 10.3.9

hello

i’ve installed ardour v 99.3 on a mac titanium powerbook g4, osx 10.3.9 // jack v. 0.74.
sound interface: rme hammerfall multiface.

ardour works great but i can’t get any of the suggested ladspa plug-in packages to work.

i’ve installed the following plug-ins from the ardour osx requirements page
http://ardour.org/requirements_osx

caps-plugins-0.3.0-2.dmg
cmt-plugins-1.15-2.dmg
swh-plugins-0.4.15.dmg
tap-plugins-0.7-3.dmg

none of these plug-ins appear in the ardour mixing strip (when i right-click on the black field below).

can someone tell me what the problem could be?

many thanks for any help.
