<path> doesn't have a problem if <pathelement> doesn't exist either,
the problem is <fileset> that insists on the dir to exist. 

You wouldn't be able to do what you want to do with a "normal"
CLASSPATH - if you could, you could use <pathelement>s as well and
you'd be done.

Hmm, if you could define the whole <path> inside a <target>, you could
use the target's if attribute (currently it's not possible to define
<path>s as children of <target>).
