rails console can't find openssl, realine problem.
rvm pkg install openssl (older format - rvm package install openssl)
rvm pkg install iconv (older format - rvm package install iconv)
rvm pkg install readline(rails console缺少的lib)
rvm remove 1.9.3
rvm install 1.9.3 -C --with-openssl-dir=\$HOME/.rvm/usr,--with-iconv-dir=\$HOME/.rvm/usr, --with-readline-6.2-dir=\$HOME/.rvm/usr
rvm 1.9.3 --default
