Does anyone know off the top of their head: Does the LPGL require
redistrbition with source availability? I know that it allows linking
with proprietary programs, but does that mean we don't have to
distribute the library source on request? And...do any of the libraries
we use in lib-src have licenses that require source distribution ala the
GPL? I know that wx and ogg/vorbis do not, but FFTW does. Are there
other GPL libraries in there? I know that I could go look, but it would
be good to know so we can determine if we need to be distributing these
sources when we make a release, and be aware when about adding
libraries. For example, to the extent that there are many GPL libraries
in there, we need to be more diligent about releasing a source tarball,
because we otherwise we are violating the license and they could stop us
from using it (not that anyone probably would go to such measures, but
it is probably within their rights).

Yes. The requirements for source distribution in the LGPL is
essentially the same as the GPL. If you distribute binary copies of a
work under the LGPL (whether or not that binary is linked to a larger
non-LGPL work), you must include either the source code or offer to
provide the source code.
A license audit of the Audacity and lib-src CVS would be a good idea.
We should also try to:
* Add "prominent notices" of changes we make to other authors'
GPL and LGPL work, as required by those licenses.
* Add copyright notices to our own source files, giving the date(s)
and author(s) of code in those files. This is mostly useful for
future users of those files who may wish to contact the copyright
* Include a written offer to provide source code on CD for Audacity
and all its libraries in our binary packages. This is not required
for our own online distribution, but it would allow others to more
easily include our packages on CDs.
