/usr/lib is always searched, and any program that uses Imakefiles (xmkmf)
will gain the rpath options automagically.

: -rpath=/usr/X11R6/lib, BTW.)

There's half a dozen ways to say it on the cc command line.  The -Wl, part
means `pass to the linker'; pkgsrc uses "-Wl,-R/path/name" because that is
compatible with ELF, a.out, 1.3.x, and 1.4 uniformly.

(a.out 1.4 packages have been built such that you don't have to edit
ld.so.conf and add /usr/pkg/lib or /usr/X11R6/lib *at all* anymore -- a.out
can use rpath, too!)

Because you have /usr/X11R6/lib in /etc/ld.so.conf.  This is, as of 1.4, a
`taboo' way of doing this.
