The NDP libraries are in a state of complete upheaval.  Instead of the  
one package ndp, there will be a set of dph packages with different  
backends to choose from (initially, there will be two backends, one  
for sequential code and one for multicore parallel code).

Due to the completely different new set up, there was no point in  
trying to track incremental changes on the wiki page.  Once, the  
individual pieces fit together again, we'll update the documentation.

Due to a sequence of problems with GHC's build system and its  
increasing Cabal'isation, the library re-arrangement has taken much  
longer than originally anticipated.  Sorry about that.
