my latest changes for procedure migrations have been pushed now:
* 12973 (HEAD -> master, origin/master, next) # Merge branch 'migrate-procedures' (2 days ago) <Tim Janik>
In particular BseProject got completely ported now.
To run this, you'll also need bug fixes from the latest rapicorn.
Rapicorn has been changed to use non-recursive make  now and suports highly paralellized builds.
I'm still working on a bunch of configure.ac and pkg-config fixes, so let me know if you run into any problems with this.
At a later point, I'll probably try to port the beast build system to use non-recursive make as well.
