$ cabal install yi
Resolving dependencies...
'yi-0.4.6.2' is cached.
Configuring yi-0.4.6.2...
cabal: alex version >=2.0.1 && <3 is required but it could not be found.
cabal: Error: some packages failed to install:
yi-0.4.6.2 failed during the configure step. The exception was:
exit: ExitFailure 1

$ cabal install yi-gtk
Resolving dependencies...
cabal: cannot configure yi-gtk-0.2.1. It requires sourceview >=0.9.11
There is no available version of sourceview that satisfies >=0.9.11

Trying cabal upgrade didn't fix it - it still throws the same error.
