Comment(by devans@…):

 I think the unfortunate naming of this port has caused some confusion.

 While the port is named 'gutenprint', it's original intent was to provide
 the gutenprint plugin for GIMP which just provides an alternative printing
 dialog.  It can be used with any printing system, including but not
 requiring the gutenprint drivers.

 The proposed +cups variant here would build the gutenprint drivers with or
 without the plugin depending on
 which patch might be used.

 These are two separate functionalities that don't necessarily depend on
 each other.

 Taking all this into consideration, I would propose to do the following:

 1) Create a new portfile (gutenprint-cups) that will install the drivers
 without the GIMP plugin. If one of the proponents of this ticket will
 provide an appropriate Portfile and accept maintainership, I will be glad
 to commit the port.

 2) Create a copy of the existing port as gutenprint-gimp-plugin and change
 dependents of the existing port to depend on this port instead.

 3) Retain the existing gutenprint port during a reasonable tranisition
 period during which it will be marked as
 {{{
 replaced_by gutenprint-gimp-plugin
 }}}
 This will cause existing installations to delete this port and install the
 new one on upgrade.  At the end of the transistion period, the gutenprint
 port will be deleted leaving just gutenprint-cups and gutenprint-gimp-
 plugin.

 I think this proposal makes the port names more understandable and allows
 people to select the functionality (one or the other or both) that is
 suitable for them without excessive use of variants.

 Any objections?
