Set the pager as appropriate at build time with:
--with-vtysh-pager=<something valid>

I use --with-vtysh-pager=cat

PIM-SM is probably broken on *bsd.  In order to get SM working we had
to add some extensions to the kernel, which I would be more than a bit surprised
that it has been done for *bsd.  I'm a bit surprised about the
-C/--dryrun issue.
We should open up some issues.

Let's open an issue here as well.

I've wondered myself about the actual usefulness of this.  I am not aware of any
benchmarks.  It's been fairly low on my list of things to do in my spare time.
