6.1_2015Q3 and X11 dependencies

[Berndt Josef Wulf <wulf%ping.net.au@localhost>]

G'day,

I'm running a headless AMD64 server without X11R7 binaries. When
attempting to update packages from 6.1_2015Q2 to 6.1_2015Q3 pkgin
returns many lines similar to


/usr/X11R7/lib/libxcb.so.1, needed by pkgin-0.9.3 is not present in this
system.
/usr/X11R7/lib/libXrender.so.2, needed by pkgin-0.9.3 is not present in
this system.
/usr/X11R7/lib/libXrandr.so.3, needed by pkgin-0.9.3 is not present in
this system.

/usr/X11R7/lib/libX11.so.7, needed by mysql-server-5.6.26 is not present

for packages that didn't require X11 libraries previously including
mysql-client and mysql-server. Most of the listed packages are not
installed on the system. Are these just warnings that can be ignored?
What am I missing?

Seasons Greetings,
