#43942: PuTTY variant without gui tools (to avoid the gtk dependency)
---------------------------------+--------------------------------
 Reporter:  shadow.mp@…          |      Owner:  macports-tickets@…
     Type:  enhancement          |     Status:  new
 Priority:  Normal               |  Milestone:
Component:  ports                |    Version:  2.3.0
 Keywords:  putty gtk2 puttygen  |       Port:  putty
---------------------------------+--------------------------------
 Right now, maports only allows to install PuTTY in full. This includes the
 GUI utilities (like putty itself) along with some CLI utils (such as
 puttygen), but requires gtk2 to build and run.

 My guess is that most people installing PuTTY on OSX would do so just to
 be able to convert PuTTY keys (.ppk) to standard OpenSSH-readable keys.
 This conversion can be done using the puttygen cli tool alone.

 PuTTY includes support for compiling only the CLI tools, avoiding the GTK2
 dependence. Hence, we could add a variant that skips building the GUI
 tools and thus does not depend on GTK2.

 The attached patch creates such variant (without making it the default and
 thus without breaking backwards-compatibility I think).
