After a bit of digging, I saw this snippet in the .cabal file for the
iconv package on hackage:
-- We need to compile via C because on some platforms (notably darwin)
-- iconv is a macro rather than real C function. doh!
ghc-options: -fvia-C -Wall
But it looks like the 'iconv' package is broken in the exact same way
for me - I get the same crazy linker errors.
