On Gentoo 2.4.19-r7 current as of 2045BST on 2002-07-22, the audiofile ebuild fails with an access violation as it tries to install /usr/share/aclocal/audiofile.m4
audiofile can be emerged if a user does: SANDBOX_DISABLE=1 emerge audiofile However, that shouldn't be necessary.
no, disabling sandbox won't do. I am working on a fix presently
the ebuild is fixed in portage. Please emerge rsync and try again (the expediency with which your rsync mirror updates may vary...)
