+If you wish to use dynamic linking, you must use
+ LD_LIBRARY_PATH=`pwd`; export LD_LIBRARY_PATH
+or
+ setenv LD_LIBRARY_PATH `pwd`

+
+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
