FreeBSD Port: lang/ruby19

[Robert Burmeister]

FreeBSD 9.2PR2 i386

More ports are provoking the error
/usr/local/lib/ruby/site_ruby/1.9/pkgtools.rb:828: stack level too deep 
(SystemStackError)
when being updated with portupgrade,
apparently due to the large number of ports that depend on them.

It takes over half a day to remove and reinstall /math/sage to update /x11/libx11.

Please look into this limitation.
