I just tried out pkgsrc but foolishly had copied /etc/mk.conf from another
system where I had set LOCALBASE=/usr/local. Is there an "easy" way to move
everything over to the default /usr/pkg? (Guessing no, as I presume some
packages code eg /usr/pkg/lib into their files, so just checking I don't
have to pkg_delete, unset LOCALBASE, remake pkg)

Cheers,

Patrick
