Actually, my problem turned out to be something else. I had installed
Berkeley DB in a non standard location and calling configure after setting
CFLAGS and LDFLAGS. The DB version check was calling cpp without using these
flags and picked up the wrong db.h. I fixed it by setting CPPFLAGS before
calling configure. 

In any case the above code in OL_BERKELEY_DB_TRY is broken. I assume the
db_env_create appeared only in db3 and the call here is only interested so
long as the linking succeeds. The way it is written however, the test
programs will segfault.
