Was it really?  I just did a build on my laptop and failed, I reverted 
this patch and it worked, I think this needs some more thought and testing.

I am running Fedora 18 with only SDL on my laptop, I get the following 
error:
> | ERROR

> | ERROR: configure was not able to find it

I think the above lines should be PACKAGECONFIG_class-native = "" and
PACKAGECONFIG_class-nativesdk = "sdl"

I think the issue is that you bring in the RDEPENDS for both the true 
and false causes above, I think that's wrong upon further review.

Sau!
