I'm not too much experienced within Gentoo portage, When I tried to install Nodejs     # emerge --ask monit nginx nodejs into my gentoo and i get an error message like:[ebuild  N     ] net-libs/http-parser-2.6.1  USE=-static-libs ABI_X86=(64) -32 (-x32) [ebuild   R    ] dev-libs/openssl-1.0.2f  USE=-bindist* [ebuild  N     ] dev-libs/libuv-1.8.0  USE=-static-libs ABI_X86=(64) -32 (-x32) [ebuild  N     ] app-admin/monit-5.16.1  USE=pam ssl -libressl [ebuild  N     ] www-servers/nginx-1.9.10-r3  USE=http http-cache http2 ipv6 pcre ssl -aio -debug -libatomic -libressl -luajit -pcre-jit -rtmp (-selinux) -threads -vim-syntax NGINX_MODULES_HTTP=access auth_basic autoindex browser charset empty_gif fastcgi geo gzip limit_conn limit_req map memcached proxy referer rewrite scgi split_clients ssi upstream_ip_hash userid uwsgi -addition -ajp -auth_ldap -auth_pam -auth_request -cache_purge -dav -dav_ext -degradation -echo -fancyindex -flv -geoip -gunzip -gzip_static -headers_more -image_filter -lua -memc -metrics -mogilefs -mp4 -naxsi -perl -push_stream -random_index -realip -secure_link -security -slice -slowfs_cache -spdy -sticky -stub_status -sub -upload_progress -upstream_check -xslt NGINX_MODULES_MAIL=-imap -pop3 -smtp NGINX_MODULES_STREAM=-access -limit_conn -upstream                                         [ebuild  N     ] net-libs/nodejs-5.6.0-r1  USE=npm snapshot ssl -debug -doc -icu {-test} CPU_FLAGS_X86=sse2 PYTHON_TARGETS=python2_7                    !!!

However, it is alsopossible that conflicting dependencies exist such that they areimpossible to satisfy simultaneously.  If such a conflict exists inthe dependencies of two different packages, then those packages cannot be installed simultaneously. You may want to try a larger value ofthe --backtrack option, such as --backtrack=30, in order to see ifthat will solve this conflict automatically.For more information, see MASKED PACKAGES section in the emerge manpage or refer to the Gentoo Handbook.After that, I try emerge --sync and emerge -u world but not fine.Some topic said I should remove ssl but I'm not sure it's a real way to solve it.
