Hi,
The orig sources in the archive, e3_2.71.orig.tar.gz, do not match the
sources available here
https://sites.google.com/site/e3editor/Home/e3-2.7.1.tar.gz
Most significantly, the version in the archive untars with errors,
while the tarball above lists or extracts without errors.
The site above also shows a newer version 2.8.2 from late 2016.
Kind regards
Felix Lechner
