I wanted to try out data parallel haskell. I followed the instructions on http://haskell.org/haskellwiki/Data_Parallel_Haskell/PackageNDP but I get the following error:
dom@lagrange:~/ghc/libraries> make make.library.ndp make: *** No rule to make target `build.library.ndp', needed by `make.library.ndp'. Stop.
The ndp libraries are currently undergoing a fundamental restructure. We'll update the instructions once matters settle down. Sorry for the inconvenience.

Manuel, I think I have things working now but the "make" system seems to have problems. I followed the instructions here: http://www.haskell.org/haskellwiki/Data_Parallel_Haskell/PackageNDP but got the messages below. On the other hand this worked: ghc --make -o dotp dotp.hs -package ndp -i../lib -threaded and then running dom@lagrange:~/ghc/libraries/ndp/examples/dotp> ./dotp 100000 --threads=1 --runs=10 +RTS -N1 N = 100000: 125/124 126/126 129/132 dom@lagrange:~/ghc/libraries/ndp/examples/dotp> ./dotp 100000 --threads=2 --runs=10 +RTS -N2 N = 100000: 80/116 86/142 96/156 which seemed to indicate I was getting a performance improvement on my dual core machine. Would you like me to raise a ticket?
