Tyson and others Would you like to gather some of what you have learned into a user-oriented Wiki page about how to use shared libraries in GHC? The right place for this is http://haskell.org/haskellwiki/GHC under "Contributed documentation". You probably have all the material in the email thread, and it's a pity not to get full value from it.
