>Description:
The x11/linux-XFree86-libs port installs X11 libraries from the
XFree86 project, compiled for Linux.  It is compatible with the
linux_base-8 port and with the pending linux_base-rh-9 and
linux_base-suse-9.1 ports (PRs 75241 and 75296).  It conflicts with
the other Linux base ports.

Separating X from the Linux base ports is advantageous because when
there is a security bug in the X libraries, package users need not
download the rest of the Linux base--and similarly when there is a
bug in another Linux base component, users need not download the X
libraries (which are much smaller than the balance).  Furthermore,
users of Linux emulation who do not need X can eschew it this way.

With this proposed macro, dependency on x11/linux-XFree86-libs can
be noted compactly.  Alexander Leidinger has prepared a list of
ports which have this dependency but for which it has not been
recorded (see PR 70539).
>How-To-Repeat:
Install linux_base-8 and any Linux software which uses the dynamic
X libraries.
