Great - it's always good to have more people working on wip.

Yes, INSTALL_DATA means it's a data file, so 644 is correct.

So that's progress, but:

So when you set it to INSTALL_SCRIPT, then pkgsrc checks a lot more
things for errors, and finds trouble

So that's a bug in the upstream code, from the pkgsrc viewpoint.  The
basic issue is that scripts need to bind at packaging time to the
interpreter that is depended on by the package.  For python this means
/usr/pkg/bin/python2.7 or something like that (depending on version),
but not "#!/usr/bin/env python".  For many scripts, the incantation is
to use REPLACE_INTERPRETER in the Makefile.   So it seems that jython is
trying to substitute the interpreter path, but it's putting in the path
to the wrkdir/destdir version, not the eventually installed version.

indeed, that sounds right.

sure - this should be substituted via ${PREFIX} so that pkgsrc installs
not to /usr/pkg will be right.

So I think you should either:

  figure out the config/substitute process in the build, or

  figure out how to REPLACE_* fix up the paths in the binaries that get

I'd look in the guide about REPLACE and at other makefiles for examples.
I am unclear on exactly what you need to do, but I hope this points you
in the right direction.
