I started an OpenGL project within an LTS sandbox as guided on another post and, somewhat foolishly it would see, I did a "cabal install cabal-install" when prompted that a new version was available.The very next time I tried to work on my code.... I got this:bash-3.2$ pwd/Users/seancharles/Documents/Coding/haskell/lts1bash-3.2$ cabal buildcabal: You need to re-run the 'configure' command. The version of Cabal beingused has changed (was Cabal-1.20.0.1, now Cabal-1.16.0).bash-3.2$ cabal configureResolving dependencies...Configuring lts1-0.1.0.0...cabal: At least the following dependencies are missing:base ==4.7.*bash-3.2$ cabal buildcabal: You need to re-run the 'configure' command.
