So there's a distribution out there where end users pull source from
Hackage, pull source for every dependency, and then build it all with GHC?
If they're not doing what distributors like Debian does--building
binaries--then what's the point of distributing at all?

True, but ouch, ultimately this is one factor that pushed me out of desktop
Linux altogether.  It's too hard to get packages for things I want to use,
and then I'm fending for myself by building things.  Centrally-planned
packaging does not scale.

He does if he uses stack.  Grab a stack binary.  It even installs GHC for
the user.
