You're installing into a cabal sandbox and compiling directly with ghc (not
cabal), but ghc doesn't know anything about the sandbox. You need to point
it to the package database with -package-db and tell it the package for
linking with -package [2].

$ ghc -package-db .cabal-sandbox/x86_64-osx-ghc-7.8.3-packages.conf.d
-package snappy HelloSnappy.hs
Linking HelloSnappy ...
$ ./HelloSnappy
HelloSnappy: foo.jpg: openBinaryFile: does not exist (No such file or
directory)
