Currently, 'shadow' has an 'U'pdate. Here's what I get when I try :
root:516 ~> emerge -pv shadow
These are the packages that would be merged, in order:

For more information about Blocked Packages, please refer to the following
section of the Gentoo Linux x86 Handbook (architecture is irrelevant):
https://wiki.gentoo.org/wiki/Handbook:X86/Working/Portage#Blocked_packages
-- end of Emerge output --
I looked at the Handbook entry cited, but it doesn't help.
No wonder, when you check the end :
"This page was last edited on 13 December 2014, at 19:42" !!
Can anyone explain what I'm supposed to make of the output above ?
How can I successfully update 'shadow', a vital system pkg ?
In case anyone doesn't know, I've been relying on Gentoo since 2003.
Most of the time, it does a very good job, but it needs some improvements.

Thanks, 'USE="-gnutls" emerge curl' appears to work.
However, where in Gentoo docs are we told that '!' = '-' ?
