As part of the process of turning Pd-extended into something that
could be included in Debian, I've made a bunch of Debian/Ubuntu
packages from some of the older, unchanged libraries that are in SVN
and included in Pd-extended. I used Launchpad to build them for
Lucid, but you should be able to just still that PPA into a Karmic
machine to use it there.

Otherwise, its easy to build the packages on your own machine since
they use the new template Makefile and debian packaging. So for
Debian or Ubuntu packages, you'd do:

cd pure-data/externals/smlib debuild -uc -us

Then you'll have a pd-smlib-.deb package in pure-data/externals.

If nature has made any one thing less susceptible than all others of
exclusive property, it is the action of the thinking power called an
idea, which an individual may exclusively possess as long as he keeps
it to himself; but the moment it is divulged, it forces itself into
the possession of everyone, and the receiver cannot dispossess himself
of it. - Thomas Jefferson
