Make very sure that your program is actually linking in the library
correctly. Linkers are weird and their interaction with build systems is
often unpredictable and sometimes perverse. Find the symbols in the
compiled library with nm and see that they aren't undefined. Use make
VERBOSE=1 to see the library actually being used.
