 unfortunately {{{webkit-gtk-2.0}}} does not build (I forgot why).

 webkit-gtk is only required for the gimp2 help browser so if you don't
 care about that you can disable it by building '''''gimp2
 -help_browser.'''''


 To be honest, I also do not know why babl was installed on my system which
 I managed to upgrade recently (see above), it presently has no dependents.

 babl is a dependency of gegl and both are used to build gimp2.  Otherwise
 you don't need it. That's why I asked.

 is not functional! I leave it to you as expert(s) what mechanism is best
 to include {{{gcc5}}} as replacement for PPC. compiler.fallback is only
 effective if a certain required compiler, say {{{clang-3.*}}} is
 blacklisted for a certain platform?

 Yes, there are a number of other tickets open with similar reports
 involving a number of specific ports that don't build on PPC due to
 compiler issues.  So the central issue is finding a compiler that can be
 built and work on PPC that will compile code written to more modern
 standards.
