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.
