 An {{{undefined reference}}} error is generated on FreeBSD at linking time
 when using dynamic libraries.  It is because of the visibility attributes
 of GCC.  FreeBSD 8.x includes GCC 4.2.1 in the base system, which behaves
 badly when the {{{#pragma GCC visibility push(hidden)}}} line is present,
 it might refer to an OS-specific error.

 Regarding the given problem, here is an excerpt from the testing log on
 FreeBSD:

 {{{

 2>&1
 Compile failed (status 256) errors were:

 *** unexpected failure for arith001(dyn)
 }}}

 It happens for both
 [http://darcs.haskell.org/ghcBuilder/builders/pgj/89/12.html i386] and
 [http://darcs.haskell.org/ghcBuilder/builders/pgj2/89/12.html amd64].
