Looks like a feature of 'sh' that regularly trips me  up.

Try inserting "; export MANPATH" after "MANPATH=/twolf7/dchen/man"

If that makes it weork the explanation is:
	'sh'  doesn't hand on variables to a subthing
	unless you tell it to with an
	export command...
	PLUS
	'[ -f $MANPATH/"$1".1 ]' is actually 'test -f $MANPATH/"$1".1'
