I tried to download the x86/Linux Binary Release arrowp-0.5-linux-i386.tgz at http://www.haskell.org/arrows/download.html ; but it failed with this message : "Not Found The requested URL /arrows/arrowp-0.5-linux-i386.tgz was not found on this server." I tried the Unix Source Release: arrowp-0.5-src.tgz, but I failed when building it on my Linux Fedora Core 6 system. I have a ghc-6.6.1 Haskell compiler and the Hugs98 (march 2005 version) Haskell interpreter. Thanks again for your help.
