Writing or debugging makefiles is something I haven't done much of, but as best I can figure out the problem is that the libcrypto.so file isn't being linked in, though this line in the Makefile in pgcrypto seems to say should be: SHLIB_LINK += $(filter -lcrypto -lz, $(LIBS)) I'm guessing it is supposed to pick up the LIBS list from the top Makefile, but isn't. If I add this: SHLIB_LINK += -lcrypto 'make clean' now passes all tests. -- Mike Nolan
