I think you should have installed Yampa via cabal, too,

cabal install Yampa

would've gotten you Yampa-0.9.2.3

I think maybe "lang" was a package way back in ancient times.
From a short look at the imports in afrob, it might be what now is 
haskell98.

Considering the homepage says "Version 0.9.1 is a minor update of 0.9, 
including a version of HGL that should compile with GHC 5.04.1"

I don't think it will be very easy to get it going now, too many API 
changes in the meantime.

It also mentions the package concurrent, which doesn't exist either.

You can try making it work by removing explicit packages from the ghc-
invocations in the makefiles and adding the --make flag
