Hi!
Cool Idea to release 1.4 sometime soon. If you could manage to get it out before ~10. of december (including C and Python bindings) we could probably have all the improvements ready for Ubuntu 9.04.
One small thing I do actually miss would be the mr-proper target callable from toplevel makefile otherwise it seems quite fine from my few tests.
EDIT:// the other thing, not only *.so but also include files going to INSTALDIR would be nice to have, too.
