fixes gimptool to install plugins into the actual plugin-directory

The Gimp plugin directory has been set to /usr/local/libexec/gimp/2.2 by means of the patched configure script.
When querying the plugin directory via gimptool-2.0:

: cmt@elch:/tmp$ /usr/local/bin/gimptool-2.0 --gimpplugindir                     
: /usr/local/libexec/gimp/2.2

But when using gimptool to actually install a plugin:

: cmt@elch:/tmp$ /usr/local/bin/gimptool-2.0 --dry-run --install-admin-bin foo
: cp 'foo' '/usr/local/lib/gimp/2.0/plug-ins'

Note the difference in target directories. When looking at gimp's tools/gimptool.c, it's obvious that get_sys_plugin_dir() does not use GIMPPLUGINDIR but constructs the plugin directory name from scratch.

Attached patch (to be dropped into files/) fixes that. Obviously, PORTREVISION needs to be increased when applying.
A quick grep through the ports tree suggests that currently no port had been using "gimptool --install...", so any chasing of gimp plugins should be unneccessary.

It looks like a downstream bug. What is the reason for the port to use patch-configure to change the plugin path?

Downstream? Upstream? I'd say upstream, as the way to determine the plugin path is clearly inconsistent. But then I don't have the energy to figure out where they keep their bugs and repos this week.

I meant downstream. The inconsistency comes from a downstream patch.

In configure.ac, the plugin directory is defined as:
gimpplugindir="$libdir/$PACKAGE/gimp_plugin_version"

In tools/gimptool.c, the file you modified, defines it as:
dir = g_build_path (..., LIBDIR, "gimp", GIMP_PLUGIN_VERSION, ..., NULL);

They should be the same. It is files/patch-configure in the port changing the the definition in configure.ac that causes the problem.
-gimpplugindir="$libdir/$PACKAGE/2.0"
+gimpplugindir="$libexecdir/$PACKAGE/2.2"

I have an installation of GIMP under my home directory for testing, and the two commands you mentioned did return consistent results.

$ gimptool-2.99 --gimpplugindir
/home/lantw44/gnome/devinstall/lib/gimp/2.99

$ gimptool-2.99 --dry-run --install-admin-bin foo
cp 'foo' '/home/lantw44/gnome/devinstall/lib/gimp/2.99/plug-ins'

I'd still argue that the real bug is upstream: the "real" plugin directory value is set in configure.ac and propagated via config.h GIMPPLUGINDIR to all the places where it might be needed. Deducing some plugindir by any other means is just inconsistent, even if it gives the same value as the upstream default.

Anyways, the more important question is how to fix this situation:
FreeBSD is settings it's own gimpplugindir "since forever" (ports r46408 from 18 years ago) - to match FreeBSD's filesystem hierarchy which is ever so slightly different from what that Linux does.
a) we could drop that modification, but then we'd have to at least rebuild all the plugins which were installed in the "modified" path (plus whatever users built and installed on their own)
b) or we modify gimptool to use the declared path and not make up another path

a might be the cleaner option (if we could argue that the plugins may live under lib/), but b looks like it will cause less breakage, so.
