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:
> * The interpreted code looks 2-3 times larger than compiled one.
> DoCon-library has size 11 Mb, =20
> .o files of compiled test take less than 2 Mb,
> test loading ghci -package docon T_ +RTS -Mxx -RTS
> needs xx =3D 12 for the compiled full test T_,
> 31 for interpreted T_.
> If DoCon-library is out of the heap reserved by -M (is it?),
> then, we have that interpreted code is 2.6 times larger.
Compiled code isn't loaded into the heap, so it isn't included in the
size you give to -M. =20
> Is this due to large interaces kept in heap?
What are "interaces"?
