Why is this worse than what the maintainer proposed:

: Basically, you can't. A while back a limitation of ghc
: wrt. libraries has been discovered.  In particular, it is only
: guaranteed that a library works with the exact version (plus
: patchlevel) of the compiler it was compiled with.  IOW, if it was
: compiled with ghc5-5.02.2-something, the Depends would look like:
:
: 	ghc5 (>= 5.02.2), ghc5 (<< 5.02.3)

it will break just as badly.
