So then you need to track down why and how to fix it... Sounds like a
case of duplicate symbols or something.

libssh2 needs to be built with debug enabled and then you need to add a call
to libssh2_trace() within libcurl to enable the debug tracing. Defining
CURL_LIBSSH2_DEBUG should also be enough. And then of course rebuild libcurl
after you rebuilt libssh2.
