This is caused by OS X's libiconv being entirely CPP macros, the

nothing to get hold of.  IIRC there's a ghc bug report open for it.

So why does it sometimes work?  I can write and compile executables
using haskeline, both with 'ghc --make' and 'cabal configure && cabal
build'.
This sounds like something I can patch haskeline to account for,  
then?
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.
Yep, darwin is OS X :)
