Hi Vojtech,

please make sure you send your mails to 854837 at bugs.debian.org and not
my private e-mail address.  Thanks.

I admit that is true and I assumed that the egg-info files would have
been cleaned up also by previous python helper versions.  Sorry for
the confusion.

To be clear about this:  Inside the .orig.tar.gz tarball you will find
the orginal source as the authors of dicompyler.  As I said its
unmaintained and orphaned code which will probably never change.
However, at least in *recent* build tools the egg-info files are cleaned
up.

I admit that's bad.  I remember that we did quite some effort to port it
to wxpython3.0 and at this time it was running.  Most probably some past
version bump of matplotlib spoiled this effort and the package was not
tested afterwards again since this is a very rarely used program (it has
currently a popularity contest vote of 2 users).

I admit I do not have a Jessie system currently at hand but you might
like to try

    wget http://ftp.debian.org/debian/pool/main/d/dicompyler/dicompyler_0.4.2-3_all.deb
    sudo dpkg -i dicompyler_0.4.2-3_all.deb

This package will be part of the next stable release Stretch and you
might be lucky that it also works on Jessie (sorry, I do not have any
Jessie system with GUI at hand but it seems it should be at least
installable.)

Kind regards

      Andreas.
