Build bot has wrong version of ruby for 1.7.x so ruby bindings are 
failing:

configure: WARNING: The detected Ruby is too new for Subversion to use
configure: WARNING: Only 1.8.x releases are supported at this time

Probably should fix 1.7.x to not try to use the none command when ruby 
isn't detected and to emit a proper error message.

RUBY=none ./configure && make swig-rb Re: buildbot failure in ASF Buildbot on svn-x64-ubuntu-gcc

FWIW, this is reproducible in trunk,

% RUBY=none ./configure
% make
% make swig-rb

I've looked into a patch.  Attached is what I came up with.  I'm not
sure there isn't a simpler way, so posting here.  The idea of the patch
is to prefix a '.swig_checked-rb' to both instances of the 'swig-rb'
targets and to check $(RUBY) in there, so 'make swig-rb' might generate
swig wrappers (if $(SWIG) != 'none') but will then fail when it gets to
the part that require a 'ruby' binary.

With the patch applied, I get:

% ./autogen.sh >/dev/null && rm -f config.cache && RUBY=none ../*ce -q && make -sj4
% make swig-rb
Ruby not found by configure
make: *** [.swig_checked-rb] Error 1
zsh: exit 2     make swig-rb
