Upgrade to perl 5.12 means no more "suidperl" (setuid perl scripts).
So we now have yet another little wrapper (security/runsuid.c) which
runs suid and whose sole function is to exec the perl script of the
same name in the /usr/testbed/suidbin directory. So a formerly setuid
perl script install now goes like:
  create /usr/testbed/sbin/mkproj as a symlink to /usr/testbed/libexec/runsuid
  install real mkproj perl script in /usr/testbed/suidbin/mkproj
When the setuid-wrapper is invoked under the name "mkproj" it execs
/usr/testbed/suidbin/mkproj. We could almost use sudo for this purpose
instead (see security/sudoers.in) but sudo loses one of the groups in
the group list.

/usr/include/utmp.h is gone in FreeBSD 9.0. In most places we nevered
needed it, but in the one case that did (tg source), it just used a
couple of the constants exposed (UT_*) and not the struct, so I just
hardwired values for the constants.

The usual tweakage to the install stuff to reflect yet another set of
packages!
