Hello, One of my test cases will not build. I am running: vigalchin@ubuntu:~$ ghc -v Glasgow Haskell Compiler, Version 6.8.2, for Haskell 98, stage 2 booted by GHC version 6.8.2 Using package config file: /usr/local/lib/ghc-6.8.2/package.conf wired-in package base mapped to base-3.0.1.0 wired-in package rts mapped to rts-1.0 wired-in package haskell98 mapped to haskell98-1.0.1.0 wired-in package template-haskell mapped to template-haskell-2.2.0.0 wired-in package ndp not found.

I guess "copyFile" is used to copy the executable to the install directory?? Regards, vasili
