  58   # first.  Gamma dlopen()s libjava from $JAVA_HOME/jre/lib{/$arch}, which is
  59   # statically linked with CoreFoundation framework libs. Unfortunately, gamma's
  60   # unique searchpath results in some unresolved symbols in the framework 
  61   # libraries, because JDK libraries are inadvertently discovered first on the
  62   # searchpath, e.g. libjpeg.  On Mac OS X, filenames are case *insensitive*.
  63   # So, the actual filename collision is libjpeg.dylib and libJPEG.dylib.

  65   # framework libraries.
