You need to set curl_ssl_nss but you cannot have this set at the same
time as any other curl_ssl* flags, the error message says you must have
exactly one of them. So you also need to set -curl_ssl_openssl as that
one is enabled by default.

Why is there an expiration date on sour cream?

That problem drove me nuts for months. I finally discovered by desperate
trial and error that un-setting the 'curl' useflag fixes it. Finally!

[walt]

Sorry, I forgot that I also un-set the 'nss' and 'openssl' useflags.
Now I have only the gnutls useflag set. (I kept that one because the
gnutls is GPL, not because I think one is better that the others.)

The only thing I insist on being encrypted are ssl connections in firefox,
so my encryption needs are minimal, maybe less than yours.

The requirements are (from the error message):

If USE=ssl then use exactly one of the following:

curl_ssl_axtls
curl_ssl_cyassl
curl_ssl_gnutls
curl_ssl_openssl
curl_ssl_nss
curl_ssl_polarssl

You have the following set for curl (per eix):

curl_ssl_openssl

But the error message also says that this is required:
net-misc/curl[ssl,curl_ssl_nss] by liboauth

You cannot have curl_ssl_nss and curl_ssl_openssl both set for curl as
liboauth complains

So, what you need to do is set

USE="-curl_ssl_openssl curl_ssl_nss" for curl

If you read my post carefully and see how all the bits fit the output
you supplied, it all makes sense. Portage output is not exactly
intuitive but it can be understood.

Or you could unset USE="curl" for liboauth.

I don't know if you'll be willing to switch from curl_ssl just to make
liboauth happy. That's your call.
