[DRE-maint] Bug#730854: gem2deb -t lowercases paths

[Christian Hofstaedtler]

Package: gem2deb
Version: 0.5.1
Severity: minor

gem2deb -t apparently lowercases paths, causing it to not find the specified sourcefile:

% gem2deb -t ~/Downloads/bundler-1.3.5.gem 
-- Creating source tarball from /home/ch/Downloads/bundler-1.3.5.gem ...

        from /usr/lib/ruby/vendor_ruby/gem2deb/gem2tgz.rb:30:in `convert!'
        from /usr/bin/gem2deb:82:in `<main>'


Notice that it calls tar with lowercased 'Downloads'.

Thanks,
  Christian
