I’m not an expert here, but you use our build recipe to build it on Solaris 11:
https://sourceforge.net/p/gar/code/HEAD/tree/csw/mgar/pkg/libexpat1/trunk/Makefile#l4 <https://sourceforge.net/p/gar/code/HEAD/tree/csw/mgar/pkg/libexpat1/trunk/Makefile#l4>

But also in our case, „make test“ fails, but the build seems to be fine.

Besides we have an up to date libexpat package in our repository. 😉
