Function missing ?

Dear Bug-hunters, 

In the documentation of 'Socket' the following is
defined :

data PortID = PortNumber PortNumber | ... -- excluded
the rest...
data PortNumber -- instance of ...
mkPortNumber    :: Int -> PortNumber

But 'mkPortNumber' is *NOT* present in the actual
implementation, which presents me with the problem that
I cannot convert an Int to a PortNumber (or PortID,
which 
is what is actually needed...).

Here is a (minimal) example of my intended usage 
(in a module intended to encapsulate communication to a 
server in a specific protocol...) :

myConnect :: String -> Int -> IO MyConnection
myConnect server port = do
    sock <- connectTo server (PortNumber (mkPortNumber
port))
    return sock

I may be that I'm in error here, but I strongly feel
that
something is missing from the 'Socket' library...

Kind Regards, Alex...
