What it doesn't say is that it's looking for parsec version 2. > P.S. Note, parsec and network are installed in the system using debian > distribution packages. For some reason the debian package maintainers decided to build everything against parsec 3 rather than parsec 2 which everyone else is using. Personally I think this was not a wise decision. Indeed it may be a problem when it comes to supporting the Haskell platform because the first version will use parsec 2. Any major parsec version transition in the Haskell platform will be made by a community decision process. What I've done is dropped the check for parsec in the bootstrap.sh. The only reason we're looking for parsec is because it's needed by network which we also need. So it's not strictly necessary that we check for it.
