Dear all, I'm a bit late to the party, but here is my $0.02:
> REQUIRED_USE=" > curl_ssl_winssl? ( elibc_Winnt ) > ssl? ( > ^^ ( > [...] > ) > )" 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. > 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.

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]).
