215If you wish to use dynamic linking, you must use
216 LD_LIBRARY_PATH=`pwd`; export LD_LIBRARY_PATH
217or
218 setenv LD_LIBRARY_PATH `pwd`
219before running make.
220
221If you are using shared libraries from /usr/local/lib
222for libdbm or libgdbm you may need to set
223 LD_RUN_PATH=/usr/local/lib; export LD_RUN_PATH
224in order for Configure to compile the simple test program
