sudo su - will reset the environment entirely, whereas sudo -s won't  
necessarily do so. You -can- configure sudo to do the approximate  
equivalent, but that's not the default behavior:
	landonf at timor:~> sudo -s
	root at timor:~> echo $HOME
	/Users/landonf

As for the original problem, heimdal should probably place it's  
binaries somewhere like:
	${prefix}/libexec/heimdal

or ...?

I tried to get heimdal to prefix all binaries with 'k' a while ago,  
but never finished. Providing a different path seems preferable,  
given that some people will want the binaries first in their PATH.
