Comment (by sunoterra):

 notice this in the log:
 {{{
 :debug:build Failed to locate 'lbzip2' in path:
 '/opt/local/bin:/opt/local/sbin:/bin:/sbin:/usr/bin:/usr/sbin' or at its
 MacPorts configuration time location, did you move it?
 }}}

 so, just to be safe, after installing {{{sudo port -cfsuv install
 libzip2}}}, cleaning {{{sudo port -v clean libvpx}}} ... an attempted re-
 installation of gimp yields the same build errors, unfortunately.
