Description: since this package features gdm as a make depend, the Arch flavored version on AUR also does so (https://aur4.archlinux.org/packages/xscreensaver-arch-logo/). The upstream version will auto-detect the presence of gdm, and does not require it to build. It is no only an optional dependency, but an optional make dependency. This is in contrast to the strict requirement for, say, intltool, which will fail when running ./configure on jwz's xscreensaver source (http://www.jwz.org/xscreensaver/).


Additional info:

* config and/or log files etc.


Steps to reproduce:
- Install xscreensaver-arch-log from AUR
- the default behavior with gdm as a make dependency will isntall 201MB of gdm and all of it's gnome dependencies
- yaourt (and perhaps other AUR tools) will not re-list gdm as unneeded by any packages, and thus will not be flagged by `pacman -Qdt`
- one who does not require/need/want the "New Login" button functionality provided by xscreensaver's lock screen login does not want gdm and all of these dependencies installed

The issue is that numerous users have complained about gdm, not wanting all of the gnome baggage that, by default, comes along with installing. graysky, the maintainer, is mimicking the behavior of this package and suggested I submit a ticket here. Technically, gdm is not only an optional dep, but an optional *make* dep as well. I'm not sure if there's any PKGBUILD syntax for that. It appears Arch builds with gdm by default, but xscreensaver will build just fine with out it. Unfortunately, if you build without it, then even having gdm installed will not provide the extra functionality.

Is there a happy solution to this conundrum? Current behavior requires the unsuspecting user to know that gdm isn't really required and manually edit the PKGBUILD to remove gdm from makedepends upon installation.
