Centos 6 Fault Restart httpd

I have had someone install or try to install SSH2 on my Centos 6 64bit Server with Direct admin as the control panel. The problem is SSH2 wasnt installed correctly and now if i try to restart the httpd it fails all the time httpd: Syntax error on line 52 of /etc/httpd/conf/[login to view URL]: Syntax error on line 4 of /etc/httpd/conf/extra/[login to view URL]: Cannot load /usr/lib/apache/[login to view URL] into server: /usr/lib64/libcurl.so.4: undefined symbol: libssh2_knownhost_init if i edit that line then another error arrives so can someone correct the fault and install SSH2 correctly
