Hmm. Nice.
What about:
BUILD_DEPENDS_EXEC=		nasm-0.98:${PORTSDIR}devel/nasm

which checks the existance with pkg_info?

BTW: I'd like something like:
BUILD_DEPENDS_EXEC=		<command>:${PORTSDIR}/some/port

That is, because maybe a port depends on an apache-port that has PHP 
installed (as an _example_) and with <command> it checks if PHP is
installed (there are at least 3 ports that install PHP, so...)

Other circumstances are easily to invent :-)

What about this?

of course you could do:
BUILD_DEPENDS_EXEC=		${PKG_INFO} -e nasm-0.98:${PORTSDIR}/some/port

or such.

Or what about an additional option to pkg_info, that checks if _at
least_ this version is installed or any higher version?

BUILD_DEPENDS_EXEC=		${PKG_INFO} --is-bigger-than 0.98 nasm-*:...

This is just an idea how it _could_ work. We need to make it perfect
:)

I have the ideas. I need comments.

Alex
