* libgcrypt11-dev on debian is a dammy file "shortcut" to libgcrypt20 . so to make possible to install atom on debian testing version we should add on depends ** libgcrypt20.
libgcrypt20 has backward compatibility to libgcrypt11 .
** libgcrypt20 is comfortable with debian unstable/testing , and ubuntu 14.04TLS .
* libgcrypt11 (without -dev) not exists on debian testing and makeing bugs with atom deb file .
