[web-devel] Strange HAppS problem (tutorial)

So, i'm working my way through the HAppS tutorial ( http:// www.haskell.org/haskellwiki/HAppS_tutorial ), and i get to section 3.2. I type in the code, it builds fine, but when i run it, i get the following error: hello: user error (decodeStringM: parsing length field failed @ "") However (and this is the strange part), if i just runghc the .hs file, it all works fine. This is running ghc 6.6, darwinports version, on intel OSX 10.4.9, however i've verified the same behavior on ghc, Audrey Tang's bundle, G4 OSX 10.4.9 (for whatever that's worth). Anyone have any ideas? Anyone run into this before? -johnnnnnnn
