devel/gauche-gaunit packing list - unexec rmdir of directory containing PORTDOCS

[Sam Lawrance]

devel/gauche-gaunit fails mtree checks, log here:
http://pointyhat.freebsd.org/errorlogs/i386-errorlogs/e.5.2005032807/gauche-gaunit-0.0.9.log

The extra directory that is left behind is listed to be deleted in the
pkg-plist when nonempty:
@unexec rmdir %D/share/doc/gauche 2>/dev/null || true

The port uses PORTDOCS. The problem seems to be that the directory is
never empty, because the automatically generated PORTDOCS entries in the
packing list are lower down than the unexec rmdir entry, eg:

@unexec rmdir %D/share/doc/gauche 2>/dev/null || true
share/examples/gauche/gaunit/site-lisp/run-test-setting.el
... etc etc ...

What to do? The only way around I can think of is to not use PORTDOCS
and list everything in pkg-plist in the right order.
