I am following an article by John Goerzen - http://www.freesoftwaremagazine.com/articles/haskell# Here, the very first example uses MissingH library. As I have ghci 7.0.3 and haskell-platform installed, I quickly installed this library using cabal. But ghc fails to find it. Here are the errors that I get - siddharth@mars:~/myprogs/hs$ ghc --make -o mh1 mh1.hs -v Glasgow Haskell Compiler, Version 7.0.3, for Haskell 98, stage 2 booted by GHC version 6.12.1 Using binary package database: /home/siddharth/tools/ghc/ghc-7.0.3/lib/ghc-7.0.3/package.conf.d/package.cache Using binary package database: /home/siddharth/.ghc/i386-linux-7.0.3/package.conf.d/package.cache wired-in package ghc-prim mapped to ghc-prim-0.2.0.0-6bf7b03ebc9c668817e4379b6796c0c2 wired-in package integer-gmp mapped to integer-gmp-0.2.0.3-91607778cf3ae8f3948a50062b4f8479 wired-in package base mapped to base-4.3.1.0-cf5fbbf5ccbd0475ad054efbb121340e wired-in package rts mapped to builtin_rts wired-in package template-haskell mapped to template-haskell-2.5.0.0-f0c8f015e470d561d64a578434331367 wired-in package dph-seq not found. wired-in package dph-par not found.
