You're partly right. The development of the Eden system itself has been
neglected for a time. Mostly because Jost Berthold (the main system
programmer) finished his PhD and left Marburg (and has only limited
spare time with his new job). The remaining members of the Eden group
here were mostly language users and language developers, not system
implementors. No one really opted to take over responsibility...
However, this is changing right now. We are actively merging the Eden
runtime and that of the GpH language (as both need basically the same
features) to get a new runtime based on GHC 6.12 (and GHC HEAD). This
runtime, while still in beta state, is already usable. However, building
it is currently still a bit too complicated to bother end users with it.
So, if your "complicated" is referring to this, you are right. We hope
to simplify this and to have a usable release in the near future. If
your "complicated" was targetting the use of the Eden language itself,
however, I object!

Of course, a source code repository for Eden always existed. The new
repository was meant for the merged version of Eden/GpH. And that exists
as well. The Eden webpage will be updated as soon as we have a
pre-release of the 6.12 branch.
