OK I've had a look at this tonight. There is a scons problem, which
lintian handily discovers for me. (Hooray lintian! I think.)

The patched build script creates symlinks such as
libscsynth.so->libscsynth.so.1.0.0. However, when scons is installing,
it doesn't install a symlink but copies the file contents. Therefore
instead of one lib file and one symlink, we get two identical lib
files - and lintian correctly reports this as an error.

I've been trying to find a way to convince scons to do the right
thing. I pushed an experimental branch to the git named
"scons_soversion" where instead of creating a symlink and asking scons
to install it, we add a symlinking command that should run during
installation. The problem is, that scons (v1.2.0) uses python chdir()
when running commands, which jumps it straight out of the DESTDIR and
tries to install in the system /usr/lib rather than the current build
tree. So I can't find a way of getting scons to create the symlink
during the install step AND inside DESTDIR. One or the other but not

If anyone can offer suggestions I'd be grateful.
