[alice@pern ~]$ ldd /usr/bin/curl |grep crypto libk5crypto.so.3 => /lib64/libk5crypto.so.3 (0x00007f4524390000) libcrypto.so.10 => /lib64/libcrypto.so.10 (0x00007f45234ca000)
What do the following show:
ldd /usr/bin/curl ldd /usr/lib64/libcurl.so.4 ldd /usr/lib64/libssh2.so.1
I can only guess you don't have the libssh2 you think you have. I just replaced curl/libcurl on a CentOS 7 system with my version built without ssh2 support:
