I have been working on it a not-so-long-time-ago and found that
this could be the best way:

[/var/db/ports/arts] edwin at k7>cat options 
# This file is auto-generated by 'make config'.
# No user-servicable parts inside!
# Options for arts-1.5.1_1,1
_OPTIONS_READ=arts-1.5.1_1,1
WITHOUT_ESD=true
WITHOUT_NAS=true

[/var/db/ports/arts] edwin at k7>eval `cat options | grep -v "^\#" | sed -e 's/^/arts_/'`

[/var/db/ports/arts] edwin at k7>echo $arts_WITHOUT_NAS
true


I hadn't put it in a PR yet because it has some synchronity issues:

- It only works for ports already installed.
- It doesn't work for ports which are being installed by this port.
- No idea how to do this for packages build on ye olde cluster.

But the idea is there:

    OPTIONS_DEPENDS=	arts
    .include <bsd.port.pre.mk>
    .if !defined arts_WITH_NAS
    BROKEN=		Please build audio/arts first before building this port.
    .fi
    .if ${arts_WITH_NAS} = "true"
    BROKEN=		This port can't work with audio/arts enabled with NAS support
    .fi
