Newbie MAKE question

[Erick Smith]

This really is a ridiculous question, but I don't have the answer, so here I 
am.

I'm trying to build qt in the ports tree using:

portinstall -f x11-toolkits/qt32

What I WANT to do is specify WITHOUT_OPENGL as per the instructions:

===> **************************************************
===> NOTE: Use of WITH_OPENGL is not recommended with
===> the NVidia drivers provided by the x11/nvidia port
===> If you use these drivers, we recommend you press
===> Ctrl-C now and set WITHOUT_OPENGL
===> **************************************************


From the port itself.  How do I do this?

Thanks,

Erick
