configure fails to correctly detect libsdl_pango universal variant

[davidstuartbruce@…]

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:
