This is almost certainly a bug, and you are at least the fourth person
affected.  Magnus Therning claimed on the #ghc IRC channel earlier to
have a complete fix, which will be published in a few hours after he's
awake again.

(As a check, you may want to try *compiling* a trivial module.  The
symptom seen by the previous three people was "Failed to load interface
for `Prelude', and the 'ghc-pkg list' reveals only ghc and rts.)
