Hi i'm a beginner in haskell and i'm trying to install Euterpea and i got this error:

An update to something in HSoM's chain of dependencies now yields this when trying to run any MUI.

GLUT Fatal Error: internal error: NSInternalInconsistencyException, reason: nextEventMatchingMask should only be called from the Main Thread!

This happens from both ghci (which has always been buggy with MUIs) and also compiled executables. I am currently looking into solutions.

Using selectOutput in a MUI on some Macs with no available MIDI output devices can cause a non-exhaustive pattern matching error.

Temporary fix: make sure you have at least one MIDI output device like SimpleSynth running before you start a program using selectOutput.

src\Data\MarkovChain.hs:18:29: error:
Module Control.Monad.State' does not exportState(State)'

markov-chain versions after 0.0.2 will also not install.

Tested on Windows 10 and OSX 10.10.5

It seems that HSoM cannot be installed
