Hi.
First thanks for the script, I used it a lot in the last years.
Unfortunately it stopped working for me, as it seems to hang at the first checked package (in my case ppp)
Could you give a hint what could cause this?
Best regards,
Martin

It's this bug: https://bugs.gentoo.org/737698

There's a new implementation from https://bugs.gentoo.org/758755 in gentoo/portage@dcbcac8.
