Yes, that does raise flags.
The haskell here:
installEnv <- getEnvironment >>= return . (:) ("GOBIN", gOBIN)
which I'd probably write as
installEnv <- (("GOBIN", gOBIN) :) <$> getEnvironment
doesn't match the python here:
GOBIN = tempfile.gettempdir()
os.environ['GOBIN'] = GOBIN
in the sense that the case for a predefined GOBIN in the environment will
lead to different results. At least I'll be surprised if otherwise.
To Matt: have you tested your haskell version? You might want to take a
look at System.Posix.Env.putenv.
