Compile-time panic

I attempted to build a program (using make) and got the following output:

ghc -odir binaries -hidir binaries --make Main.hs -optl-w
ghc: panic! (the 'impossible' happened)
  (GHC version 7.6.3 for x86_64-unknown-linux):
	While parsing "/home/taymonbeal/.ghc/x86_64-linux-7.6.3/package.conf.d/package.cache": too few bytes. Failed reading at byte position 8

Please report this as a GHC bug:  http://www.haskell.org/ghc/reportabug
