I've attempted to follow these steps for Unity 5.0.2 on Mac with no luck. One issue is the version of FSharp.Core.dll - there does not appear to be one for 2.3.0 as mentioned in the writeup. I've tried used one from 4.0 and 4.5 also with no luck. Even downloaded the DLL from this repo. But in all cases I can't seem to build the project & my .fs files show with errors in MonoDevelop.
