Comment:

 I finally tried to compile
 [http://oriya.sarovar.org/docs/gettext_single.html a simple gettext
 example program] I found:

 {{{
 #include <libintl.h>
 #include <locale.h>
 #include <stdio.h>
 #include <stdlib.h>
 int main(void) {
         setlocale(LC_ALL, "");
         bindtextdomain("hello", "/opt/local/share/locale");
         textdomain("hello");
         printf(gettext("Hello, world!\n"));
         exit(0);
 }
 }}}

 It builds with:

 {{{
 gcc -I/opt/local/include -L/opt/local/lib -lintl -o hello hello.c
 }}}

 Then I tried to build universal:

 {{{
 gcc -I/opt/local/include -L/opt/local/lib -isysroot
 /Developer/SDKs/MacOSX10.4u.sdk -arch ppc -arch i386 -lintl -o hello
 hello.c
 }}}

 It fails when trying to find libiconv, which gettext uses:

 {{{
 /usr/libexec/gcc/i686-apple-darwin8/4.0.1/ld: for architecture i386
 /usr/libexec/gcc/i686-apple-darwin8/4.0.1/ld: warning can't open dynamic
 library: /Developer/SDKs/MacOSX10.4u.sdk/opt/local/lib/libiconv.2.dylib
 referenced from: /opt/local/lib/libintl.dylib (checking for undefined
 symbols may be affected) (No such file or directory, errno = 2)
 /usr/libexec/gcc/i686-apple-darwin8/4.0.1/ld: Undefined symbols:
 _libiconv referenced from libintl expected to be defined in
 /opt/local/lib/libiconv.2.dylib
 _libiconv_open referenced from libintl expected to be defined in

 _libiconv_set_relocation_prefix referenced from libintl expected to be
 defined in /opt/local/lib/libiconv.2.dylib
 collect2: ld returned 1 exit status
 }}}

 Because I specified `-isysroot` but not `-liconv` it thinks it's supposed
 to look for libiconv in the MacPorts prefix ''inside the sysroot'' --
 inside /Developer/SDKs/MacOSX10.4u.sdk -- but of course there isn't any
 MacPorts prefix inside the SDK. If I add `-liconv` it knows not to prepend
 the sysroot and works fine:

 {{{
 gcc -I/opt/local/include -L/opt/local/lib -isysroot
 /Developer/SDKs/MacOSX10.4u.sdk -arch ppc -arch i386 -lintl -liconv -o
 hello hello.c
 }}}

 So I imagine that the configure script is doing the same thing, is not
 using `-liconv`, and when the program fails to compile, it assumes this is
 because gettext doesn't exist.

 The easy fix is to add `-liconv` to the `configure.ldflags` which I did in
 r46175.
