Configure of wget fails with message: checking for libgnutls... no configure: error: --with-ssl was given, but GNUTLS is not available. (Use flag "ssl" is enabled) Manual installation of gnutls solves the problem
Ditto on Linux amd64 (and probably all other arches).
To use openssl (instead of gnutls) the configure script needs the option --with-ssl=openssl otherwise it will look for gnutls. Perhaps the ebuild should offer a choice between openssl and gnutls by checking for the gnutls USE flag. The gnutls USE flag could override the ssl USE flag in a similar way to app-admin/gkrellm.
