Hi. I was trying to install SMTPClient-1.0.1 Compiler reported me: ierton@vault SMTPClient-1.0.1 % cabal build Preprocessing library SMTPClient-1.0.1... Building SMTPClient-1.0.1... [1 of 2] Compiling Network.SMTP.ClientSession ( Network/SMTP/ClientSession.hs, dist/build/Network/SMTP/ClientSession.o ) Network/SMTP/ClientSession.hs:242:16: Not in scope: data constructor `Message' Network/SMTP/ClientSession.hs:406:15: Not in scope: data constructor `Message' I've made some digging: Seems that newest version of 'hsemail' (1.6) breaks backward compatibility (SMTPClient depends on it) My questions: 1) Where should i send bugreport to? There are no emails on http://hackage.haskell.org/package/SMTPClient so i don't know how to contact maintainers. 2) How to fallback hsemail? i tried: ierton@vault ~ % cabal install hsemail-1.3 # good, i suppose ierton@vault ~ % ghc-pkg hide hsemail-1.6 # Bad one ierton@vault ~ % caball install -v SMTPClient ... ... bla-bla ... ... selecting hsemail-1.6 (installed or hackage) and discarding hsemail-1.0, 1.1, 1.2, 1.3, 1.4 and 1.5 ... Looks like hiding a package is not a case for me. ps I am using ghc-6.12 -- Thanks, Sergey
