OK, Stefan was right. The arrows package is an extension of Control.Arrow, not a from-scratch
implementation. The name confused me. Perhaps a better name would be "arrows-ext" or something
like that.

Thanks, but this doesn't answer the question. I can load up the
Control.Arrow module fine in ghci. Is there a problem with the
packaging information?
I did a google search, and this problem has come up on IRC, but nobody
figured out what was causing it as far as I can tell.

I'm using ghc 6.6.1 compiled from source (by me) on Debian Linux. I
thought that arrows were included with the ghc distribution. Does
anyone know what's happening and how to fix it?
I don't know what's happening, but you can get arrows easily enough from
http://hackage.haskell.org (our CPAN).
