Fwd: ghc build dependencies

Hi everyone,

I was trying to install ghc and faced the same problem with
ghc-bootstrap 7.0.4_0 as others.

But I was trying to install a prebuilt package of ghc.  It is ghc
@7.6.3_4 +gcc48.
ghc-bootstrap is stated as build dependency.  But I don't build anything.
As far as I can imagine there is no need in ghc-bootstrap in this case.

So I wonder is ghc-bootstrap really required for installing prebuilt
ghc package?  (I don't mean port implementation details. :)

The cost of installing ghc-bootstrap is quite high
$ du -hs /opt/local/share/ghc-bootstrap
647M /opt/local/share/ghc-bootstrap
 98M /opt/local/var/macports/software/ghc-bootstrap

It also costs 98Mb of traffic, not just disk space.
Imho, it is not worth to do all that extra stuff and use that much
extra disk until it is actually required.

By the way, ghc-bootstrap @7.0.4_1+gcc48 still fails
