lowdown not helped by snowleopardfixes

[Jan Stary]

Hi Ken,

when I created the textproc/lowdown port not long ago
https://github.com/macports/macports-ports/pull/1241
you kindly advised me to use

	PortGroup snowleopard_fixes 1.0

so that older MacOS sysem without e.g. strndup(3)
can still compile lowdown.

However, it seems that the compilation still fails,
at least on my 10.5.8 and 10.6.8. The snowleopardfixes port
compiles and installs just fine, providing

$ nm /opt/local/lib/libsnowleopardfixes.dylib
0000000000001d46 s  stub helpers
                 U ___error
0000000000000000 t __mh_dylib_header
                 U _getc
0000000000001ad9 T _getdelim
0000000000001ac7 T _getline
                 U _malloc
                 U _memchr
                 U _memcmp
                 U _memcpy
0000000000001c1c T _memmem
                 U _realloc
0000000000001bca T _strndup
0000000000001a8c T _strnlen
0000000000001cbc T _wcsdup
                 U _wcslen
                 U _wmemcpy
                 U dyld_stub_binder


But when building lowdown itself (full log below)
it fails on a missing strndup(3). The failing line is

	/usr/bin/gcc-4.2 -o lowdown main.o liblowdown.a -lm
	Undefined symbols:
	"_strndup", referenced from:
	_xstrndup in liblowdown.a(xmalloc.o)
	ld: symbol(s) not found
	collect2: ld returned 1 exit status

The installed snowleopardfixes library doesn't seem
to even enter into it at all. Am I missing something
obvious about how the snowleopard_fixes portgroup
is supposed to work?

	Jan
