Post-v25 fixes

This pull request resolves some pretty minor issues discovered after v25 was tagged. The commit messages are self-explanatory.

In your reply to #50, you stated that you did not want 'gem2arch' listed as a dependency here; however, to be consistent with e6ac27b, I added this change at the end of this pull request. If you really don't want 'gem2arch' (or 'pkgfile') as dependencies, feel free to ignore the last commit here, and I can send you another pull request to remove 'pkgfile' from the depends array.
