  62   # first.  Gamma dlopen()s libjava from $JAVA_HOME/jre/lib{/$arch}, which is

  64   # unique searchpath results in some unresolved symbols in the framework
  65   # libraries, because JDK libraries are inadvertently discovered first on the
  66   # searchpath, e.g. libjpeg.  On Mac OS X, filenames are case *insensitive*.
  67   # So, the actual filename collision is libjpeg.dylib and libJPEG.dylib.

  69   # framework libraries.
