Thank you for your prompt answer.


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.
