>Description:

Building graphviz with make && make replace failed as follows:

===> Updating using binary package of graphviz-14.1.5
/usr/bin/env  /usr/sbin/pkg_add -K /var/db/pkg -U -D /usr/pkgsrc/graphics/graphviz/work/.packages/graphviz-14.1.5.tgz
pkg_add: graphviz-14.1.5: missing required library: /usr/pkg/lib/libcdt.so.5
pkg_add: graphviz-14.1.5: missing required library: /usr/pkg/lib/libcgraph.so.6
pkg_add: 1 package addition failed
*** Error code 1

Those are the prior versions of libs installed by graphviz; the
behavior is caused by graphviz's build linking bins against the
versions in /usr/pkg/lib instead of the versions it just built.
That's not supposed to happen, and ideally the wrappers wouldn't allow
it.

Removing the prior version before building works around the problem.
It will also obviously only surface, and at least theoretically only
matter, after a major version bump.

The prior version appears to have been 12.2.1nb5, so before the three
updates this spring.

>How-To-Repeat:

Install old graphviz, build new, make replace.

>Fix:

Remove elder gods from build system.
