Unable to build graphics/libEGL on 10.0 but not on 9.2

[Kata Goto]

Hi all,

is there differences with make.conf beetwen 9.2 and 10.0?
I have this make.conf (into poudriere) : http://bpaste.net/show/347960/
On the 9.2 graphics/libEGL compiles, but on 10.0 it is ignored with this
message : "Ignored: Please enable WITH_NEW_XORG, libEGL needs libdrm higher
then 2.4.24".

This errors comes from
https://github.com/freebsd/freebsd-ports/blob/master/graphics/libEGL/Makefile#L26
but what's weird is that I have this "WITH_NEW_XORG=yes" at line 1 which
might evaluate .if ! defined(WITH_NEW_XORG) to false.

Thanks by advance for your help.
