Darcs still has no concept of branches. I quite like that. It gives a  
better overview on your file system. Every "branch" is still laid out  
like you would have it in SVN or something like that.

I would mark that problem as a problem of you build-system or you  
workflow.

If I want to branch, I usually don't create a new repos as my branch  
and start working there, instead I put the momentary state away in  
another repos and continue working on my active repos. Then, I push  
patches back to the "old repository" or pull patches from somewhere  
else. This ensures that all "temporary data" is still in my active  
"working repository". Sure, it only goes so far until I merge the  
branches changes back into the "old repository", but thats when I  
prefer to do a full check (and eventually rebuild) anyways.

My biggest problem with Darcs is that I have yet to run into the  
dreaded merge problem. It is said not to be rather tame in > 2.0, but  
I have yet to experience it. So I can't make an assessment on that.
The Darcs command line interface is one of the best I ever  
experienced. At least when it comes to my workflow, you mileage may  
(and will!) vary.
