Hi,

While I don't *really* care which way this is solved, it is indeed
a problem. Johan Visagie <wjv@FreeBSD.org> already 'solved' this for
his mail/mailman port, the structure of which I picked up and
used in my emulators/xmame port.

Here are the relevant parts of my port (warning: cut & paste so no tabs):

files/pkg-opts snippet:

------->8----->8----->8----->8-------

# Variable|Default value|Short description
#       Multi-line/long description (optional).
#       Multi-line/long description lines must start with whitespace!
#
WITH_ASM68K|no|If set to 'yes', this will enable the speedier but buggy
        assembler 68x00 CPU emulation cores. This will only work on x86.
        Note that some games are known to break with this option, among
        them pbobble2.

------->8----->8----->8----->8-------

The actual Makefile code (could be in bsd.port.mk if standardized):

------->8----->8----->8----->8-------
pre-everything::
=2Eif !defined(BATCH)
        @${TEST} -r ${PKGOPTS} && \
          (${ECHO_MSG} '---------------------------------------------------=
----------------------'; \
          ${ECHO_MSG} 'Perform a "make options" to see a list of available =
installation options.'; \
          ${ECHO_MSG} '----------------------------------------------------=
---------------------';)
=2Eendif

options:
        @(${ECHO_MSG} "=3D=3D=3D>  Build options for ${PKGNAME}:"; \
          ${PERL} -ne '/^#/ || /^\s/ && print || \
            print sprintf "* %s [%s]\n  %s", split(/\|/)' ${PKGOPTS}) | \
          $${PAGER:-/usr/bin/more}
------->8----->8----->8----->8-------

Do a 'make options' in /usr/ports/emulators/xmame to see the result.
