If you are looking for something with features akin to ClearCase, then Vesta
would probably do the trick. The only downside is that I don't think it has
really caught on outside of Compaq/HP/Intel. Vesta is licensed under LGPL
and was originally developed in DEC's (and later Compaq & HP) SRC research
lab. It is a complete build management system complete with caching of
build objects and the overall build environment. A completely different
beast from subversion which only does revision control.

I don't know how active the development is, but the lead developer can be
reached at xorian@users.sourceforge.net
