  # The gamma launcher runs the JDK from $JAVA_HOME, overriding the JVM with a
  # freshly built JVM at ./libjvm.{so|dylib}.  This is accomplished by setting 
  # the library searchpath using ({DY}LD_LIBRARY_PATH) to find the local JVM 
  # first.  Gamma dlopen()s libjava from $JAVA_HOME/jre/lib{/$arch}, which is
  # statically linked with CoreFoundation framework libs. Unfortunately, gamma's
  # unique searchpath results in some unresolved symbols in the framework 
  # libraries, because JDK libraries are inadvertently discovered first on the
  # searchpath, e.g. libjpeg.  On Mac OS X, filenames are case *insensitive*.
  # So, the actual filename collision is libjpeg.dylib and libJPEG.dylib.
  # To resolve this, gamma needs to also statically link with the CoreFoundation 
  # framework libraries.
