 Hi,

 Both tuxmath and tuxtype depend (optionally) on libsdl_pango.  The i386
 build correctly detects and uses libsdl_pango.

 When attempting to build the universal variants of tuxmath or tuxtype,
 tuxtype's configure incorrectly reports that libsdl_pango is not found.
 This is done in a dedicated macports installation with exclusively
 universal port variants:

 {{{
 bash-3.2$ sudo ./tuxport installed libsdl_pango
 The following ports are currently installed:
   libsdl_pango @0.1.2_0+universal (active)
 bash-3.2$
 }}}

 The upstream configure for tuxtype is just a standard AC_CHECK_LIB, and
 the other SDL dependencies (libsdl, libsdl_mixer, libsdl_image, and
 libsdl_ttf) are all correctly identified with the same technique.

 Below is the relevant excerpt from tuxtype's config.log:

 {{{
 configure:14636: checking for SDLPango_Init in -lSDL_Pango
 configure:14671: /usr/bin/gcc-4.0 -o conftest -O2 -isysroot
