[SDL] building nonroot-dga sdl?

I suppose some explanation is in order.
It's a patch to the XFree86 DGA library.  You need to get the source
to XFree86 to use it.  Once you've applied the patch and built the DGA
library, you then need to remove the .so version of the library (if you
have it) and then link SDL with it.  Any applications using this version
of SDL will be able to use DGA on systems that have framebuffer console,
without requiring root permissions.

The binary RPM on the website has been built this way.

See ya,
