dnl  There are two things going on here. We need to know where the dx installation
dnl  is so we can get the CLASSPATH info from the javainfo file and we need
dnl  to know where to install the samples. Typically this would be in the 
dnl  dx install directory--but allow users to override with --prefix.

dnl  Locate the dx installation. If not found then can default to where it would
dnl  go with a default install of OpenDX.
