I was thinking that pkgsrc should have a method that allows installing
binary packages (if available). Maybe using environment variable
"USE_BINARY_PKG". If it is set, then look in PACKAGES (or use *PKG_URL),
before attempting any build from source.

I see in Packages.txt: "... you can use the the "bin-install" target,
which will install a binary package - if available - via pkg_add ..."

But no other details about this "bin-install" target. It doesn't look to
be implemented completely in bsd.pkg.mk.

Can anyone explain this? Provide (or point me to) further documentation?

Or is my idea not implemented? If not, is anyone interested?

Thanks,
