If you keep this line, you will get no problem because it use the buildlink
from the package - renderext.
I remove this line and add USE_BUILTIN.*=yes for all of them
(because PREFER_NATIVE=yes is broken), xfree 4.5 is new enough for compiling
packages(at least glib2, gtk2, firefox...etc. that I have already tried.)
