Hi, a refresh release of the Haskell (lib)curl package has been uploaded to Hackage, http://hackage.haskell.org/cgi-bin/hackage-scripts/package/curl It enables 6.10.2 use, taking into account the updated story on how to register Haskell-based finalizers. Thanks to Carl Howells for reporting this problem. Bug reports / feature requests etc. most welcome, btw. enjoy --sigbjorn
