lots of mucking around with sed deleted...

As an alternative solution I'd use a symbolic link to the bin and
delete it and recreate it as required.

if your three bins are: /home/insight/sparc/bin/itahost
			/home/insight/sparc/bin/itaqc
			/home/insight/sparc/bin/itasc

set path = (. /usr/ucb /bin /usr/bin /usr/local/bin ~/itabin)

alias host  'rm -f  ~/itabin ; ln -s /home/insight/sparc/bin/itahost'
alias qc    'rm -f  ~/itabin ; ln -s /home/insight/sparc/bin/itaqc'
alias sc    'rm -f  ~/itabin ; ln -s /home/insight/sparc/bin/itasc'

(you don't need to rehash, at least not on my machine)
