Does this depend on a certain version of gcc? $ ghc -M --make Matrix.hs -o matrix Chasing modules from: Matrix.hs [1 of 2] Compiling Fu.Prepose ( Fu/Prepose.hs, Fu/Prepose.o ) ghc-6.5.20051207: could not execute: gcc-3.4.3 I'm wondering why it is trying to execute something which isn't in my path...

Simon fixed this recently. The GHC HEAD build will not re-link with --make if none of the object files have changed.
