If the swig file was the problem, you should be fine.

This doesn't have anything to do with the modtool version, but the
version of your code structure. If you don't know what this means,
you're probably on post-3.7, but 'gr_modtool info' will tell you for
sure.

Yep, this is the bug that was fixed a while back.

I just pushed a fix to the standalone, perhaps that help.

Note that I'll only be doing easy bugfixes to the standalone version
since modtool was merged.
