I'm sure not afraid of having subversion access, but I don't think I
need it right now. Gentoo Packages ideally consist of only one file
(called "ebuild") plus additional patches if needed. And I'm looking
forward to include the ebuilds in the Gentoo Sunrise Project.

Well, took me some time to figure it out too :-)

Yes, I think so. I made Gentoo packages for the "splitted" packages and
it seems to work.
If somebody wants the AllInOne-Package, the following has to be in
.cmake.cache:
LIBS+= -Lyade-lib/yade-lib-wm3-math/bin -Lyade-lib/yade-lib-algorithms ...
INCLUDES+=-Iyade-lib/yade-lib-wm3-math/src/yade-lib-wm3-math -I...
And then you should be able to build everything before installing.

That's good news!

I would be interested to help since I'm studying Physics which is
somehow related :-)
