/usr/pkg/bin/demo should be renamed?

demo needs some python component

configure says:
 /usr/pkg/tmp/pkgsrc/new/korelib/work.rainier/korelib-1.0/missing: Unknown `--run' option
 Try `/usr/pkg/tmp/pkgsrc/new/korelib/work.rainier/korelib-1.0/missing --help' for more information
 configure: WARNING: `missing' script is too old or missing
(but probably doesn't matter)

Use LIBTOOL_OVERRIDE (if still necessary) instead of LTCONFIG_OVERRIDE;
but:
LIBTOOL_OVERRIDE=${WRKSRC}/libtool
causes:
ltconfig: unrecognized option `--build=i386-unknown-netbsdelf1.6'
Try `ltconfig --help' for more information.
configure: error: libtool configure failed
