Hi,In trying to install Tidal, following something that worked for someone else who was getting an error similar to one I got, I ran ghc-clang-wrapper. I believe it was after that that cabal install stopped working, and I lost a lot of libraries that used to exist, such as Sound.MIDI:GHCi, version 7.8.3: http://www.haskell.org/ghc/ :? for helpLoading package ghc-prim ... linking ... done.Loading package integer-gmp ... linking ... done.Loading package base ... linking ... done.Prelude> import Sound.MIDI<no location info>:Could not find module ‘Sound.MIDI’It is not a module in the current program, or in any known package.Prelude>When I try to reinstall a library that used to exist -- e.g. "hosc", below -- via cabal install, I now get a giant slew of failures.Any ideas?Many thanks,Jeffsh-3.2# cabal install hoscResolving dependencies...In order, the following will be installed:binary-0.7.2.2 (new version)data-binary-ieee754-0.4.4 (reinstall) changes: base-4.7.0.1 added,binary-0.7.2.2 addednetwork-2.6.0.2 (new package)text-1.2.0.0 (new package)blaze-builder-0.3.3.4 (reinstall) changes: base-4.7.0.1 added,bytestring-0.10.4.0 added, text-1.2.0.0 addedhosc-0.15 (new version)Warning: Note that reinstalls are always dangerous.
