What you need to run Haskell in prison

I want to run a simple Haskell program from a closed environment that I create myself. The following Haskell program I want to run is:

import System.IO

main = do
    hPutStrLn stderr "test standard error!"
    hPutStrLn stdout "test standard out!"

It just prints a string to stderr and stdout, works great outside of prison. The code compiles as follows:

ghc -O2 --make -static -optc-static -optl-static $MAINHS -optl-pthread -o bin/run_ai

I get the run_ai executable that runs the program, as I said, this works great outside the prison. Below is the material that is put in jail, and I think that something is missing there, because when I run the program in jail, it does absolutely nothing, it does not even exit, and error / output dumps are not set at all.

mkdir -p lib64 lib bin

cp /bin/sh bin/
