When I first installed FreeBSD I was able to run "halt" and "reboot" as

Here is the output of echo $PATH:
/sbin:/bin:/usr/sbin:/usr/bin:/usr/games:/usr/local/sbin:/usr/local/bin:
/usr/X11R6/bin:/home/Dave/bin:/usr/home/Dave/apache-forrest-0.7/bin

My question is with /sbin in the path why do I have to
specify /sbin/reboot, /sbin/kldstat etc.?  Could this be causing my make
install to fail?  How can /sbin be in the path and still require a full
path declaration for it's commands to work.
The short answer to your question is that if /sbin really were in your path you would be able to run programs from it, therefore /sbin is *not* in your path. (Since you can run commands from /sbin with full path names it can't be file permissions or deleted programs). Either that or something else on you path is somehow messing up your shell big-time, but that seems less likely.

You say that the problems started after you changed you path (I assume in your .profile or whatever). So, quite simply, you must have made some kind of mistake. I would suggest going back to the file you edited and starting again. Comment out the PATH specification and add things back one at a time. Assuming a /bin/sh or derivative, you can re-load your file with
   . filename

(for csh derivatives, use "source filename").

After each change you make, source the changes and see if you can run some innocuous program from /sbin such as kldstat.
