Hi Michael,

- From what I can tell, /usr/ports/devel/pcre++/Makefile has some
constructs in it that perform a similar function.  Perhaps it will give
you something to go on.

Essentially, you can pull in libnet11-config with a LIB_DEPENDS, then
run the libnet11-config tool to populate CONFIGURE_ENV with CFLAGS and
LDFLAGS.  That should avoid using the != construct.

Hope that helps,
Greg
