Do you have the readline-devel RPM installed?  This is needed to compile
GHC with readline support.

/share is created when there is documentation to install.   Probably you
didn't install the documentation (it isn't installed by default).

There's a pre-formatted version on the GHC web site:

        http://www.haskell.org/ghc/docs/latest/set.ps

Compiled code isn't loaded into the heap, so it isn't included in the
size you give to -M.

What are "interaces"?
