Please try EXIFR, http://rubyforge.org/projects/exifr

  gem install exifr

It's a pure ruby EXIF reader so it works on both windows and linux.
Please file a bug in the tracker at rubyforge if GPSInfo is not read
properly/ at all and send me some examples (including the expected
results) since I don't have any files containing GPSInfo.

Thanks,
Remco
