I think there is another option. I've found on the ghc wiki that
compile time can be greatly reduced by disabling optimisations. They
say that time goes down to minutes compared to hours needed for
optimised build. We can add option to ghc spell to disable
optimisations. What you think about it?

I think you misread it. I proposed to change all spells that depend on
GHC to depend on ghc (only on ghc, not ghc-bin). Then everything will
work until we decide something on ghc-bin.

I think this is possible. The only problem (aside from hacking
installation procedure) i see is package.conf (a.k.a
pain_in_my_ass.conf). This file has some intermediate format, it's
text, but not human readable/editable (probably serialised haskell
data). There is a tool to manage this file called ghc-pkg. To delete
package you need corresponding .cabal file and ghc-bin tarball doesn't
provide us these, although we can try and find them.
