Hello, Gentoo. For the past couple of days, after $ emerge --sync, I've tried
$ emerge -auND @world .. It has come back very quickly with the error message: ######################################################################### !!! The ebuild selected to satisfy ">=net-misc/curl-7.21.5[ssl]" has unmet requirements. - net-misc/curl-8.1.2::gentoo USE="adns ftp gnutls http2 imap pop3 progress-meter smtp ssl tftp -alt-svc -brotli -gopher -hsts -idn -kerberos -ldap -mbedtls (-nghttp3) -nss -openssl -rtmp (-rustls) -samba -ssh (-sslv3) -static-libs -telnet -test -verify-sig -websockets -zstd" ABI_X86="(64) -32 (-x32)" CURL_SSL="openssl -gnutls -mbedtls -nss (-rustls)" The following REQUIRED_USE flag constraints are unsatisfied: curl_ssl_openssl?

( openssl ) curl_ssl_rustls? ( rustls ) ######################################################################### .. I don't understand what is meant by "curl_ssl_openssl? ( openssl )" in the above message. I assume it's talking about some USE flag, but which? openssl? curl_ssl_openssl? As a matter of interest, I have =dev-libs/openssl-3.0.9-r2 installed. Please help me understand what's happening. Thanks for the help! -- Alan Mackenzie (Nuremberg, Germany).
