[cp-patches] Fix for OSX build

[François Revol]

Hi,
I recently tried to build microjonas on jamvm+classpath, using OSX
10.6, and I had to work around the antlr test in classpath:
- the jar built by MacPorts is located in /opt/local/lib,
- the sed regexp used to figure out the antlr version seem to be
specific to GNU sed...

The attached patch fixes both.

François.
