The binary library packages are tied to the specific package they were built against.
Everything in the [haskell] repo needs to be bumped and re-built for the new GHC version.

For now, I just commented out that repo in pacman.conf and am building from ABS with yaourt.

Three cheers for the [haskell] repo maintainers!

Everything else that I've tried to upgrade fails:

haskell-csv
-----------

warning: cannot resolve "haskell-filepath=1.1.0.4", a dependency of "haskell-cs\
v"
:: the following package(s) cannot be upgraded due to unresolvable dependencies\
:
     haskell-csv

But on hackage, csv 0.1.2's package description does not require
a specific version of filepath.  I suppose that something in the
package building process ties this to the version of haskell-filepath
for a particular version of GHC, and that similar remarks apply to
the other packages below, and a lot of others.

haskell-pandoc
--------------

warning: cannot resolve "haskell-http=4000.0.9", a dependency of "haskell-pando\
c"
:: the following package(s) cannot be upgraded due to unresolvable dependencies\
:
     haskell-pandoc

But the package description for pandoc 1.8.1.1 says

HTTP (≥4000.0.5 & <4000.2),

haskell-gtk
-----------

-bash-4.2# pacman -Ss haskell-gtk

-bash-4.2# pacman -Ss haskell-gtk
haskell/haskell-gtk 0.12.0-3
   Binding to the Gtk+ graphical user interface library.

Concluding request
------------------

I think our [haskell] repo maintainers are probably aware of the
problems, but since I've not heard any news from them about this
since GHC 7 went into extra, I just wanted
to make sure.  I believe there are 199 packages on the repo, so
this is a lot of work and I'm prepared to be patient.  It would
just be nice to hear a little from the repo maintainers about
their progress and/or plans -- for example, announcements about
individual packages being made ready.

Thanks again for all of your valuable work.

Greg
