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
