# Note: coreutils ends up linking against /usr/lib/libiconv, despite having

#   /usr/lib/libiconv.2.dylib (compatibility version 7.0.0, current version 7.0.0)
# My guess is that this is some bad interaction between --with-libiconv-prefix and
# --with-libintl-prefix, based on this configure output:
#   checking how to link with libiconv... -L/opt/libiconv-1.16/lib -liconv
#   checking how to link with libintl... -L/opt/gettext-0.21/lib -lintl -liconv -Wl,-framework -Wl,CoreFoundation
# You end up with some correct lines:
#   gcc-4.2 -std=gnu99   -mcpu=7450 -O2   -o src/factor src/factor.o src/libver.a lib/libcoreutils.a -L/opt/gettext-0.21/lib -lintl -liconv -Wl,-framework -Wl,CoreFoundation lib/libcoreutils.a  -L/opt/libiconv-1.16/lib -liconv 
# and some which are incorrect:
