The description for CURL_SSL USE_EXPAND flags appears to be in /usr/portage/profiles/desc/curl_ssl.desc Just in case this wasn't mentioned yet in the thread, and to make sure it's mentioned explicitly: CURL_SSL=openssl is expanded to curl_ssl_openssl as a USE flag. So my understanding is that the openssl flag controls building the curl part that can use openssl, and curl_ssl_openssl selects that part to be used for SSL. >From a quick (hopefully not *too* quick) glance at the ebuild, I think this is because curl can be built with more than one SSL backend (the USE flags that appear in USE=...), and the CURL_SSL=... USE_EXPAND flags control which one gets to be the default. (But someone more knowledgeable please correct me if this is wrong or incomplete.) -- Nuno Silva
