+You may be mixing the Tru64 cc/ar/ld with the GNU gcc/ar/ld.
+That may work, but sometimes it doesn't (your gcc or GNU utils
+may have been compiled for an incompatible OS release).
+
+Try 'which ld' and 'which ld' (or try 'ar --version' and 'ld --version',
+which work only for the GNU tools, and will announce themselves to be such),
+and adjust your PATH so that you are consistently using either
+the native tools or the GNU tools.  After fixing your PATH, you should
+do 'make distclean' and start all the way from running the Configure
+since you may have quite a confused situation.
