 Replying to [comment:6 gparent]:
 > I'm sorry, I didn't phrase this correctly. The .hi files weren't in the
 package I downloaded, they were remnants from an earlier compile of the
 package that I did myself.

 > So what happened is, I compiled readline-1.0.1.0 for version god-knows-
 what, and then I tried rebuilding it with a newer GHC version, without
 cleaning, and I ran into those .hi related errors. No 64-bit involved in
 the entire process. Just different GHC versions after a package upgrade.
 runhaskell Setup.hs clean (or if that doesn't work, rm -rf dist), then
 rebuilding, fixed the problem.

 Ok, then I'm still slightly mystified, as GHC should have detected that
 the old `.hi` files were from a different GHC version and emitted a
 suitable error message.  Well, in the absence of any evidence we'll have
 to leave this one closed.
