Comment (by t.tensi@…):

 Dear all,

 sorry for provoking such a long discussion thread, but now I am a bit
 lost.  Shall I provide a port patch
 * just for the 9.5.1 update?
 * Or 9.5.1 plus the variant "x11" with a default of +x11 and no checking?
 * Or 9.5.1 plus the variant "x11" with an intelligent check for X11
   for calculating the default variant?

 The current productive Portfile blindly assumes X11, because the
 configuration is always
 done as {{{make X-Configure}}}.  This bombs on Quartz-only configurations
 (like mine).
 Here a {{{make Configure}}} should be done instead.

 My proposal: Michael as the port owner shall decide on how to proceed and
 I will provide the patch as required.

 But be aware that I have a PPC Tiger system only, so some verification
 will be required ;-)

 Best regards,

 Thomas
