Seems easy to fix but I can't even find where on my drive I can find the source code.
Where is the source?
You need to run 'cabal unpack yi' in a suitable directory. This will create a subdirectory containing the source. Enter that subdirectory, make the changes and then run 'cabal install' from that subdirectory. Regards, Kapil. --
