Don't get me wrong -- the socket support is pretty decent, but there are also some weird idiosyncrasies, for example requiring that the PortNum is specified in network byte order and lacking a function to convert host->network byte order (hton).
Look at Haddock for PortNumber: newtype PortNumber Constructors PortNum Word16 Instances Enum PortNumber Eq PortNumber Integral PortNumber Num PortNumber Ord PortNumber Real PortNumber Show PortNumber Typeable PortNumber Storable PortNumber Try it in ghci: Prelude Network.Socket> 15 :: PortNumber 15 Prelude Network.Socket> PortNum 15 3840 Prelude Network.Socket> (fromIntegral (15::Int))::PortNumber 15 So, in essence, there are *many* functions that let you do this. You should not be needing to construct PortNum by hand.
