Error about SSLProtocol when starting Apache

I just installed Apache 2.2.6 & when trying to start it i got this:
Invalid command 'SSLProtocol', perhaps misspelled or defined by a module not included in the server configuration

Any help?

Did you enable the mod_ssl.so module?

Is there a way to do so after i ran configure or i should rerun configure again?

Check whether you have previously compiled mod_ssl but not enabled that. If so, you may find the mod_ssl.so in the modules directory and you simply need the "LoadModule" to enable it.

Otherwise, you will need to re-configure and then re-compile your Apache.
