the default ./configure compile on RH 6.0 does not work.  It selects GDBM which
doesn't seem to be supported and also tries to define strdup improperly.

It does seem to work using the db api.

./configure --enable-ldbm --with-ldbm-api=db

to fix the strdup problem I removed the else statement from the 

#ifndef HAVE_STRDUP statement on line 49 of /include/ac/string.h

These changes allow all of the tests to pass.
