Compile it and link against the static libreadline.a in the build
directory.  You could try adding "LDFLAGS='-L /usr/local/lib' to the
`make' command, but that's not guaranteed to work, since Mac OS X
insists on linking against its own incomplete readline "emulation" in
/usr/lib in many circumstances.  I've had to change the bash and
readline makefiles to link against absolute pathnames on Mac OS X
because of the linker behavior.
