Now I remember a case where <bsd.port.options.mk> with <bsd.port.mk> has
broken the amavisd-new port (patch was submitted by me ... :< ) with the
affect the existing config was overwritten.
http://www.freebsd.org/cgi/cvsweb.cgi/ports/security/amavisd-new/Makefile.diff?r1=1.72;r2=1.73
corrected Makefile
http://www.freebsd.org/cgi/cvsweb.cgi/ports/security/amavisd-new/Makefile.diff?r1=1.73;r2=1.74
I suspect if <bds.port.options.mk> is removed (like r71) nothing will change.
