So this is hilarious. This whole time I thought 'warning' meant 'error'.
I rebuilt all of ghc and the platform with 7.0.3, and did it again. Now it
complains about containers.
Went ahead and installed anyway (duh!). Now it looks like it worked. I'll
check back if it didn't work.
I can't believe I never tried to just install the darn thing...
