 Attached you find an updated port file for the most recent release of
 XOTcl.

 Since i am listed as maintainer (listed as wu.ac.at:neumann), i tried to
 update the port myself via svn, but i seem to have no svn account (see
 https://trac.macports.org/wiki/CommittersGuide/Distfiles "neumann" or
 "neumann at wu.ac.at" did not work as userid).
