This is what I saw during last emerge of ca-certificates: >>> Configuring source in >>> /var/tmp/portage/app-misc/ca-certificates-20140223.3.15.5/work ... >>> Source configured. >>> Compiling source in >>> /var/tmp/portage/app-misc/ca-certificates-20140223.3.15.5/work ... make -j5 -C /var/tmp/portage/app-misc/ca-certificates-20140223.3.15.5/work/ca-certificates/mozilla make: Entering directory '/var/tmp/portage/app-misc/ca-certificates-20140223.3.15.5/work/ca-certificates/mozilla' python certdata2pem.py Ignoring certificate "UTN-USER First-Network Applications".
