no you were clear, my issues with WITHOUT_RUBY are the same as WITH_RUBY
1: no way to turn it off, WITHOUT_RUBY=="no" is still defined so the
branch is taken. This is generally not how I would expect things to
happen, I said no and no is no.
2: too general, it should be WITHOUT_SUBVERSION_RUBY. I might want
ruby some where else
basically once it is in /etc/make.conf you are screwed with the .if
defined(X) method and that is my real problem with it and in the
course of an upgrade/install I want to update all installed
dependencies I have no control over which individual ports get X and
which do not get X, some ports have large dependency trees on other
ports and I am stuck with 1 value for all of them.

we tend to meet any new situation by reorganizing, and a wonderful method it
can be for creating the illusion of progress, while producing confusion,
inefficiency and demoralization."
