Comment 1 for bug 907330

Another FTBFS was there after merging Rob's gstreamer support patches:

It seems the /usr/include/GLES2/gl2ext.h header from libgles2-sgx-omap4-dev package defines GL_TEXTURE_EXTERNAL_OES, but that is specific to sgx driver. To make the XBMC working on all platforms, this define should be available in generic mesa header.
