This fix will address GGUS ticket 58560: "glite-GLEXEC_wn makes uses of GLEXEC_LOCATION instead of GLITE_LOCATION" The script will build-up a BASEDIR. The GLEXEC_LOCATION will be used first, with a fall back to GLITE_LOCATION and if that is not set, the "/opt/glite" directory will be used as a best guess.
