except for some bits (such as libc), we do not store contrib code in the
SVN. So don't be afraid to check it out. In some subdirectories (which
we call repositories - more on that in  'doc/getting_started.txt'), in
particular 'qt4', 'libports', and 'ports', you will find a 'Makefile',
which downloads and prepares 3rd-party source codes.

Please have a closer look at the 'qt4' subdirectory. I think, it is
exactly what you describe, several patches plus the custom glue code to
adapt qt4 to our userland.

We use the SVN merely for distributing the code. It is updated every
three months when a new Genode release arrives. In between, only small
fixes are committed.

It's the same concept as for our 'qt4' port. Downloading and patching
the 3rd-party sources is done by the Makefile in the 'libports'
repository. For the versions of the individual packages, please have a
look at the respective Makefile snippets 'libports/ports/'.

Good luck
