Comment (by ballen4705):

 The problem I am now seeing is the following:

 {{{
 --->  Configuring gimp2
 --->  Building gimp2
 Error: Failed to build gimp2: command execution failed
 Error: See
 /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_graphics_gimp2/gimp2/main.log
 for details.
 }}}

 From gimp2/main.log:

 {{{

 wilber.svg 24/gimp-wilber.svg

 }}}

 Is there a simple way to modify libgexiv2.2.dylib so that it will
 internally say that it supports 3.0.0?  If so I would be grateful for
 instructions about how to do this.
