* Using boost over 1.60.0 causes compile errors. This is a known boost bug. Also, dyninst-9.2.0 is set to be the vesrion of dyninst to use with OSS, as of now. The newer version fails to build.
* Fix bad syntax in specifying the boost version range.
* Update the version numbers for the krell institute components and tools: cbtf and openspeedshop.
* Do not build glib for qt3, it is not needed and causes build problems at this time anyway.
* A fix was added for setting LD_LIBRARY_PATH in the qt3 build, but if LD_LIBRARY_PATH is not set the qt build fails. So so check and set LD_LIBRARY_PATH if not set, update if it is set.
* Update the fix for qt3 build by setting LD_LIBRARY_PATH instead of checking for whether it is set or not per Adams comment that spack clears LD_LIBRARY_PATH.
* A fix was added for setting LD_LIBRARY_PATH in the qt3 build, but if LD_LIBRARY_PATH is not set the qt build fails. So so check and set LD_LIBRARY_PATH if not set, update if it is set.
