If the changes you make are in the ports files, porttools has a `port
diff` command (which uses a reference ports tree to create diffs
against. You can use /usr/ports as that reference, and in fact I believe
that is the default.

You can then just port diff > path-to-patch-file.diff, ready for
attachment into a new bugzilla issue.

If the patch is against WRKSRC source code, you can

a) cp WRKSRC/file WRKSRC/file.orig
b) edit file
c) make makepatch (from the port dir)

makepatch recursively searches WRKSRC for *.orig files, and
automatically creates correctly named patch-foo patch files in /files
for you.

Hope that helps
