I found this error in the Gentoo Linux distro when I used the emerge command and return me this text:
1 2 3 | ... The ebuild selected to satisfy ... |
Open the /etc/portage/make.conf uncomment the old USE row and use this:
1 | USE="-* X acl alsa" |
The /etc/portage/make.conf file is used to customize the Portage environment on a global level to every package that is emerged.
The USE variable allows the system-wide setting or deactivation of USE flags in a space-separated list.
