haskell-src-exts should depend on happy
Hi, cabal installing haskell-src-exts fails, because of an unlisted dependency to the happy executable. The following succeeds: cabal install happy; cabal install haskell-src-exts Thanks, Ozgur

It does list a dependency on happy: Build-Tools: happy >= 1.17 If I understand correctly, the problem is that cabal does not track packages which only install executables. So all it can do is give an error if a 'happy' executable is not found; there is no way to have it automatically install happy if it is not. This is a well-known limitation of cabal-install rather than a problem with the haskell-src-exts package in particular. -Brent

Yep, what Brent said. See this ticket: http://trac.haskell.org/haskell-src-exts/ticket/59 Cheers, /Niklas
