[Haskell-cafe] strange link error

[Brandon Allbery]

In that case you were missing part of the error message, since it came
up at 2 out of 3 compiled and referenced "command line" instead of an
object file, and comes before the "Linking" message.

Given the forced link stuff I wonder if you need -Wl,-u
-Wl,hkl_binoculars_cube_free (or some variant thereof).
