I have just done a pull and reconfigure. `which ghc` /run/current-system/profile/bin/ghc I created a one line hello world program: ```haskell main = putStrLn "hello, world" ``` Then I tried to compile it with ghc. I get this error. `ghc Main` [1 of 1] Compiling Main ( Main.hs, Main.o ) gcc: error trying to exec 'as': execvp: No such file or directory `gcc' failed in phase `Assembler'. (Exit code: 1) I have tested compiling the same hello world program with the same ghc command and it works fine on a none Guix System.
