+If you wish to use dynamic linking, you must use 
+	LD_LIBRARY_PATH=`pwd`; export LD_LIBRARY_PATH
+or
+	setenv LD_LIBRARY_PATH `pwd`
+before running make.
+
+If you are using shared libraries from /usr/local/lib
+for libdbm or libgdbm you may need to set
+	LD_RUN_PATH=/usr/local/lib; export LD_RUN_PATH
+in order for Configure to compile the simple test program
