While emerging vino: WARN: unpack QA Notice: ${WANT_AUTOCONF} variable unset. Please report on http://bugs.gentoo.org/ QA Notice: ${WANT_AUTOMAKE} variable unset. Please report on http://bugs.gentoo.org/
Fixed by definining WANT_AUTOCONF to latest and WANT_AUTOMAKE to 1.9 in both versions of vino currently in the tree. automake-1.10 fails on my machine with the following (hence using 1.9, not latest for WANT_AUTOMAKE): make[4]: Entering directory `/var/tmp/portage/net-misc/vino-2.16.0/work/vino-2.16.0/server' test -z "/usr/libexec" || "/var/tmp/portage/net-misc/vino-2.16.0/image//usr/libexec" /bin/sh: /var/tmp/portage/net-misc/vino-2.16.0/image//usr/libexec: No such file or directory make[4]: *** [install-libexecPROGRAMS] Error 127 while this succeeds with 1.9: make[4]: Entering directory `/var/tmp/portage/net-misc/vino-2.16.0/work/vino-2.16.0/server' test -z "/usr/libexec" || mkdir -p -- "/var/tmp/portage/net-misc/vino-2.16.0/image//usr/libexec" /bin/sh ../libtool --mode=install /bin/install -c 'vino-server' '/var/tmp/portage/net-misc/vino-2.16.0/image//usr/libexec/vino-server'
