Comment(by gui_dos@…):

 In Mountain Lion, the expr command provided by Apple is based on the
 FreeBSD version and not on the old NetBSD one.

 ML's expr doesn't interpret correctly the single backslash. I found that
 another effective workaround consists in
 escaping the single slash from:
 {{{
 if expr "$link" : '/' > /dev/null; then
 }}}
 into
 {{{
 if expr "$link" : '\/' > /dev/null; then
 }}}

 The launcher script of jython suffers from the same problem.
