The top problem using the tool is that the gifinter executable is no longer installed by graphics/giflib. The recommended workaround -- to declare:
`focr_bin_gifinter ..../convert -interlace`
does not work. When `sa-learn` is invoked, for example, it complaints "Cannot find executable for gifinter".
This patch installs a shim making things work again -- with either ImageMagick's or GraphicsMagick.
I have the following reservations about it:
1. The script is installed into $PREFIX/bin instead of some location private to the port.
2. Perhaps, the script should be provided by giflib instead...
3. The *proper* way to fix this problem is to make the code respect the focr_bin_gifinter-setting...
