from a manual ./configure checking for DirectFB... configure: WARNING: *** DirectFB 0.9.9 or newer is required. The latest *** version of DirectFB is always available from http://www.directfb.org. Also, why make those DEPENDs optional if in econf they are declared as needed...?
notice how it's a 'warning' ... the configure script keeps on going and at the end says 'directfb disabled' in econf it does `use_enable directfb` ... dunno what you're talking about really ...
Guess I was thrown off by the words "DirectFB 0.9.9 or newer is required", required being the keyword there. Didn't matter though - this snapshot is missing the clanPNG headers completely (says the feature is enabled, by compiling code that includes clanPNG fails horribly with unable to find library).
well please file another report w/output because png compiles just fine on my box ;)
