Hmmm. Just for kicks I deleted my amanda installation and used
sysinstall to install the package from the 3.3-RELEASE CD-ROM (on a
machine running FreeBSD 3.3-RELEASE + KAME 19991018 snapshot):
roosevelt:amanda% pwd
/usr/local/libexec/amanda
roosevelt:amanda% ls -ls rundump runtar
4 -r-sr-x--- 1 root operator 3196 Sep 11 04:54 rundump
4 -r-sr-x--- 1 root operator 4076 Sep 11 04:54 runtar
I'm not saying the original poster didn't see what he thought he saw,
but I don't think the blame for this can be laid on the package
installation or sysinstall either.

In the case of FreeBSD's ports collection (and packages generated from
it), the exact parameters used to configure amanda can be found in:
/usr/ports/misc/amanda24/Makefile

Yes. (Or, alternatively, build using something like the FreeBSD ports
collection to gain some package management features, but verify the
configure- and build-time options before installing, which is what I've
been doing.)
