[BioC] Failed installing SJava on MacOS (success!)

Hi all,
Michael, your debugging details inspired me and this morning Martin and
had some time to dig for a solution.
There were a couple of issues. The FindClass call was failing because
the RForeignReference class depends on native code and the required
"DLL" was not being found. The reason the "DLL" was not being found was
because the wrong path was being set for java.library.path -- R now uses
an architecture-specific subdirectory of $PACKAGE/libs (e.g.
$PACKAGE/libs/x86_64). In addition, Java is looking for a .dylib not a .so.
In any case, we've updated the source for SJava in svn, and you can
checkout the latest to give it a try:
svn co --username=readonly \
--passowrd=readonly \
https://hedgehog.fhcrc.org/bioconductor/trunk/madman/Rpacks/SJava
Please let us know if it works for you.
There are still some outstanding issues on OS X. In particular, GUI
code that uses the AWT classes are not currently working.
