Bugzilla Bug 200661

I have been trying to get splashy to work on gentoo and ran into a small
directfb bug that seems to have been around for some time.

When DirectFB is built with the "sysfs" USE flag linking against the library
fails  with the following errors.

then mv -f ".deps/splashy-splashy_functions.Tpo"
".deps/splashy-splashy_functions.Po"; else rm -f
".deps/splashy-splashy_functions.Tpo"; exit 1; fi

I tracked this down to directfb itself, directfb-config does not set -lsysfs
so linking against it fails as noted above.
I went looking into why this was happening on Gentoo and not other distros and
it seems this is because they are ALL patching the DirectFB sources.
I have attached a simple patch that fixed the problem.
Please add this patch to the ebuild. I have tested it in my overlay and it
works as it should.

Patch against DirectFB-0.9.25.1

should really convert the additional libs to Libs.private

Libs: -L${libdir} -ldirectfb
Libs.private: @THREADLIB@ @DYNLIB@ @ZLIB_LIBS@ @SYSFS_LIBS@ @OSX_LIBS@

fixed in DirectFB-1.1.0 ... thanks for the report/patch !

i'll see about opening a bug report upstream about the Libs.private thing
