Dear all,
I'm a bit late to the party, but here is my $0.02:

I don't like this. If the user specifies several SSL providers in
make.conf, it should mean that any of these is fine and the ebuild can
choose an arbitrary one. The exactly-one-of operator would cause emerge
to complain in this case and possibly force the user to have complex
package.use setups.
That's a good point and not one that I wasn't aware of. But how would
we better design this? The only thing I can thing of (suggested
earlier) is an eclass with some intelligence. I'm not sure of the most
userfriendly way of doing this.
With the number of ssl providers growing, like libressl, and with
issues like bug #510974, I think its time we consider making this a
uniform way of dealing with ssl providers in gentoo. We would proceed
something like this:
1. Introduce a new USE_EXPAND called SSL which mirrors CURL_SSL ---
becuase CURL_SSL is too provincial a name.
2. migrate curl and all its dependencies to the SSL use expand.
3. Migrate over all consumers of ssl to the new SSL use expand system.
What do people think?
I think a better name for the USE_EXPAND would be CRYPTO_PROVIDER (or
similar) instead of just SSL, as the libraries are not strictly used for
SSL but also for other forms of crypto (e.g. [1]).
Agreed.
