This sounds like it did not indeed install in the sandbox (compare the notice after "Resolving dependencies" in the hakyll install). Unfortunately I don't know what follows from here; it sounds like a cabal bug to me, but maybe being in the patched pandoc source directory keeps it from seeing the sandbox, in which case maybe there's an option to point to a specific sandbox for installs? (I still don't have a working Haskell install on my new machine, and am not sure at this point when I'll be able to get to it, sigh.)

Thank you for the help. I wonder if I need to set this up as a shared sandbox so that pandoc gets installed to the sandbox in the parent directory. Kind of like the first example from the “Advanced usage” section of:

Creating a shared sandbox ended up working. I don’t know it that’s the proper way to do this kind of thing. For reference, here is what I did to get Hakyll installed with the broken Pandoc dependency: $ mkdir hakyll $ cd hakyll $ cabal sandbox init --sandbox . $ cabal install -j hakyll [compilation fails at Pandoc] $ cabal get pandoc-1.13.1 $ cd pandoc-1.13.1/ $ cabal sandbox init --sandbox ../ [make trivial source change] $ cabal install -j $ cd .. $ cabal install -j hakyll I’ve not tested the Hakyll installation yet to see if it works properly, but the installation succeeded.
