recognize source png

Component:  ports     |    Version:  2.3.3
 Keywords:  cursor    |       Port:  gimp2
----------------------+--------------------------------
 After having just done a `selfupdate` and `upgrade outdated`, I'm trying
 to install ufraw which requires gimp2.  I didn't previously have gimp
 installed.  After the compilation fail, I tried to `sudo port clean --all
 gimp2` and then reinstall, but the error remains the same.  From the
 install log:


 {{{

 :info:build         echo $image | \
 :info:build           sed -e 's|.*/||' -e 's|-|_|g' -e 's|\.png$||' >>
 tool-cursors.list; \
 :info:build         echo "  ./$image" >> tool-cursors.list; \
 :info:build       done )
 :info:build ( rm -f color-picker-cursors.list; \

 }}}

 I attempt to run the gdk-pixbuf-csource command myself, but still get the
 same problem.

 In the error message (both when run by hand or when done via ports), it
 complains about the file `cursor-color-picker.png`.  I can view that file
 with Preview - it looks like a color picker.  I can identify the file with
 ports' ImageMagick.

 Because I just updated, I have the most recent port of libpng if that
 matters:

 {{{
 $ port installed libpng
 The following ports are currently installed:
   libpng @1.6.18_0 (active)
 }}}
