Pretty much what the summary says: darcs-2.0.2 fails to compile, and it appears the error is "src/Workaround.hs:24:32: Module `System.Posix.Internals' does not export `FDType'". There are a bunch of other warnings both before and after this error appears, but since this is the only one immediately followed by "make: *** [src/Workaround.o] Error 1 \n make: *** Waiting for unfinished jobs....", I think it's the relevant error.
Please, try to use darcs-2.4.4-r1 (it will be filled for stable request soon).

Emerging it would require ~arch unmasking the following packages: dev-haskell/zlib dev-haskell/haskeline dev-haskell/mmap dev-haskell/hashed-storage dev-haskell/terminfo dev-haskell/binary dev-haskell/dataenc dev-haskell/extensible-exceptions I'll do so anyway, if you think it'll help, but still, this doesn't look like a package that's close to hitting stable.
Sergei or I will post the request as soon as we can.
Closing as WONTFIX as 2.4.4-r1 gone stable as a result of bug #352438
