Can't use home-grown packages with ghci on Mac OS X

Platform: Mac OS X (10.3.3)
  (works fine on Linux)

Ghc Version: 6.2.1
  (same error with both
    the binary built by Wolfgang Thaller
    and version built from source using darwinports)

gcc version: 3.3

Problem:
  ghci doesn't work with user generated packages.

Details:

  While trying to track down why I'm getting this error message for
  a user-built package (which seems a little suspicious):

    ghci -package galois

    GHCi runtime linker: fatal error: I found a duplicate definition 
for symbol
       __module_registered
    whilst processing object file
       /Users/tullsen/r/gd/src/build/lib/galois.o
    This could be caused by:
       * Loading two different object files which export the same symbol
       * Specifying the same object file twice on the GHCi command line
       * An incorrect `package.conf' entry, causing some object to be
         loaded twice.
    GHCi cannot safely continue in this situation.  Exiting now.  Sorry.

  I created a trivial package and now I get the following (bus error):

    $ ghci -package mytest
       ___         ___ _
      / _ \ /\  /\/ __(_)
     / /_\// /_/ / /  | |      GHC Interactive, version 6.2.1, for

    \____/\/ /_/\____/|_|      Type :? for help.

    Loading package base ... linking ... done.
    Loading package mytest ... Bus error

In both of these cases, I can compile, link, and run without problems.
My files are as follows (also attached as tar file):

------- Makefile -------
libmytest.a: Test.hs
        ghc -package-name mytest -c Test.hs
        rm libmytest.a
        ar qvs libmytest.a Test.o

install: libmytest.a mytest.pkg
        rm mytest.o  # -g not updating this
        ghc-pkg -u -g < mytest.pkg
        ghc-pkg -s mytest

testghci:
        ghci -package mytest Main.hs

testghc:
        ghc -o main -package mytest Main.hs

------- Test.hs -------
module Test where

succ2 :: Int -> Int
succ2 x = x + 2

------- Main.hs -------
module Main where
import Test

main = print $ succ2 0

------- mytest.pkg -------
Package { name = "mytest",
          import_dirs  = ["${PWD}"],
          source_dirs  = [],
          library_dirs = ["${PWD}"],
          hs_libraries = ["mytest"],
          extra_libraries = [],
          include_dirs = [],
          c_includes   = [],
          package_deps = ["base"],
          extra_ghc_opts = [],
          extra_cc_opts  = [],
          extra_ld_opts  = []}
