Wow. I've never seen this happen before. This error means that the
SSL_CTX_callback_ctrl() function returned a failure... that function is
basically only used for the verbose option so not using -v probably hides this

Although you getting this problem more likely indicates something really weird
that I cannot explain. Why would you get a problem to set a callback? Huge
amounts of people use libcurl 7.15.1 with openssl 0.9.8a fine already without
that error...

Sorry, but I don't know what else to say!
