 Here is a patch to update mzscheme to version 4.1.5.

 I patched the configure script to allow the "unixstyle" option on Mac OS X
 -- it's usually disabled for OS X because they want to build a directory
 with the frameworks & their GUI apps, not just install the Unix parts of
 the software to Unix places.

 I mailed the plt-dev list and they OK'd the change
 (http://list.cs.brown.edu/pipermail/plt-dev/2009-May/000877.html).

 As a result the Portfile is a bit simpler and installs files in the
 correct places (the mzscheme port @375 installed header files in
 /opt/local/include directly instead of /opt/local/include/plt for
 example).

 I did not do any heavy testing ; however launching the mzscheme binary and
 running some simple Scheme programs does work.
