>Description:

        mail/mutt-devel looks for a mail spool on the build host to
        determine statically where to look for mail.  This is wrong,
        and breaks if you build it in a chroot with no mail spool, for
        example.

>How-To-Repeat:

        Built mutt-devel in a chroot with no mail spool.

>Fix:

        I have worked around it by adding

CONFIGURE_ARGS+=        --with-homespool=yes
