How can I set port options?

[G_Nerc]

With the new ports infrastructure, has the way to configure port options changed? It looks like:

portname_OPTIONS= WITH_X11 ...

But I need to set the variable USE_GCC only for emulators/virtualbox-ose and emulators/virtualbox-ose-kmod. How do I do this?

Why would you need to set that variable? It's usually best to leave it up to the port maintainer which compiler to use. And in the case of emulators/virtualbox-ose you can see that this has already been addressed, when looking at it's Makefile you'll come across this entry:

USE_GCC=        any

Which means so much that this port uses GCC by default.

Now, the other port (emulators/virtualbox-ose-kmod) does not specify something like this, but this one seems to have the GCC usage hard coded into the Makefile. You can see this when checking out the configure arguments:

HAS_CONFIGURE=  yes
CONFIGURE_ARGS+=[I]--with-gcc="${CC}"[/I] --with-g++="${CXX}" --nofatal \
                --disable-xpcom --disable-sdl-ttf --disable-pulse \
                --disable-alsa --disable-dbus --disable-python \
                --build-headless

So there really is no need to try and force the usage of GCC somehow, these ports are already configured to do just that.
