Build failure using GHC 7.6.3 on Mavericks

[marcpaterno]

I have encountered a failure to build pandoc-1.12.3.1, using GHC 7.6.3 on OS X Mavericks. The output is long, but most of the bulk is warnings. The error that stops the build for me is the following:

[17 of 55] Compiling Text.Pandoc.ImageSize ( src/Text/Pandoc/ImageSize.hs, dist/build/Text/Pandoc/ImageSize.o )

src/Text/Pandoc/ImageSize.hs:201:17: Not in scope: `lookAhead'
Failed to install pandoc-1.12.3.1
cabal: Error: some packages failed to install:
pandoc-1.12.3.1 failed during the building phase. The exception was:
ExitFailure 1

This failure does not seem similar to earlier bug reports I found, which report on difficulties in the ghc on Mavericks, because the complaint is about the Haskell code itself.

I'd be happy to provide the full log file, if that is useful.

What version of binary are you building against?

Hello John,

According to what I find in my ~/.cabal/lib directory, I am building against binary-0.6.4.0. If I should be looking elsewhere for this information, please let me know where to look.

best regards,
Marc

Ah yes, this bit me with zip-archive too. lookAhead was removed between
binary 0.5 and binary 0.6. It should be possible to work around this,
though. I'll look into it when I have a chance.

This just bit me too. The version on hackage is 1.12.3.1. Many users will be using ghc 7.6 with binary >= 0.6, so will experience this problem if they cabal update && cabal install pandoc today. Perhaps commit a333d97 is worthy of a minor version bump and upload to hackage?
