OK, then, I have another question.
At a glance of the Makefiles in pkgsrc, the syntax

  1.	NO_CDROM=	"the reason ..."

is generally used, but this causes fantastic result by "make FOR_CDROM=YES".

	% cd /usr/pkgsrc/net/socks5
	pino:/usr/pkgsrc/net/socks5 % make FOR_CDROM=YES
	===> socks5-1.0.2 may not be placed on a CDROM: NEC
	has
	a
	funky
	license
	for
	this
	software

The syntax

  2.	NO_CDROM=	the reason ...

seems to work as expected.
Which syntax should I use?

I'm not on this mailing list.  Please Cc: me replies.

Thanks,
