Hi, I wanted to install it with cabal. Well $ cabal install derive Resolving dependencies... cabal: Couldn't read cabal file "./derive/0.1.2/derive.cabal" As I traced a little, it seemed that line: 'build-depends: base == 4.*, syb' was wrong.
Sigh. This is the problem with adding new syntax. I'll have a go at adding a check so that packages using this new syntax should have to declare cabal-version: >= 1.6.
Fortunately the solution for end users is easy:
$ cabal update $ cabal install cabal-install
To get the latest version which groks the new syntax.
