Don't you still need a 'do' somewhere in there?

  main = do
    xmonad $ gnomeConfig 
    { terminal = "urxvtcd" 
    } 
    `removeKeysP` ["M-b", "M-."]

should compile.

I think all on one line looks more readable though:

  main = do
    xmonad $ gnomeConfig { terminal = "urxvtcd" } `removeKeysP` ["M-b", "M-."]


Apologies if this doesn't work, I haven't compiled it myself.
