has problems building against radiusclient1-dev (which might not be
our fault, but...). so, for the time being we're shipping an updated
version of ltmain.sh in the diff (build depending on the newest version
of libtool is subobtimal for backporting).
* add --disable-rpath to configure options... arg, and i had to apply
another patch to ./configure to keep a -R from sneaking in and
deactivating it.
* upstream ./configure fails to automagically detect mysql installation now,
so modify debian/rules accordingly.
* modify debian/control to be more explicit about build-dependencies to
make life easier for backporting.
