Package: libwx-perl Version: 1:0.9923-4+b1 Severity: normal libwx-perl depends on libalien-wxwidgets-perl, which in turn depends on libwxgtk3.0-dev and from there a bunch of X11-related development headers and documentation.
This means installing e.g. needrestart-session turns the machine into a development machine. I believe development headers should be needed only during build. One fix is probably a Debian-specific patch to not depend at runtime on libalien-wxwidgets-perl, because we handle that using package metadata. - Jonas
