The trouble is that if you install python modules anywhere else than to
those directories reported by the python binary, they won't be usable (at
least not without further hacking like requiring users to define
PYTHONPATH to find pyecasound after installation).
So we have two approaches:
1) not install any python stuff by default
2) install python stuff to a directory that is not known by the
python interpreter
... neither seems very good. :(

See (2) above.

Yes, this is true. But, but, specifying /usr/local is not enough to find
out where to put the python stuff. This is why we have the
--with-python-modules option.

Ignoring installation errors in not a good idea either (might hide real
bugs in the build scripts).

Ecasound's configure already prints out the python isntallation locations
in its configure summary. It's then user's responsibility to run "make
install" with sufficient privileges to install files to those
directories.
Anyway, suggestions are welcome. I'd really like to solve this problem
before the next release.
