Yes, for sure it is.  If /usr/X11R6/lib is not in /etc/ld.so.conf (or
whichever file is used in netbsd), then the system is broken.

Indeed: in Debian, this is done in the postinst script of package xlibs:

$ fgrep ld.so /var/lib/dpkg/info/xlibs*
/var/lib/dpkg/info/xlibs.postinst:if ! grep -qs ^/usr/X11R6/lib\$
/etc/ld.so.conf; then
/var/lib/dpkg/info/xlibs.postinst:  echo /usr/X11R6/lib >> /etc/ld.so.conf

Hopefully!

Yes, and we should document this somewhere.
