>Description:

        After bootstrapping pkgsrc on various linux and solaris systems and 
trying to
        build net/sipcalc, I get the following error:

ERROR: This package has set PKG_FAIL_REASON:
ERROR: [bsd.options.mk] One of the following options must be selected: inet6
*** Error code 1

        It's very cumbersome for the end-user to have to make such decisions.
        Each options that must be set should have a reasonable default, possibly
        determined at bootstrap time.  The package can still display a warning
        (as I think it would) if the option is set to indicate what it is and
        what it could be, but bailing out on a default installation saying
        "I don't know what to do" is not very user friendly at all.

>How-To-Repeat:
        cd /usr/pkgsrc/bootstrap
        ./boostrap
        cd ../net/sipcalc
        bmake
