Given a default zabbix server installation on FreeBSD, the libcurl depedency is not compiled with support for cookies. When executing a web monitoring scenario, the server's logs has a line like:

web scenario "Main Page" error: could not set cURL option [10031]: An unknown option was passed in to libcurl

1) It would be nice if the command passed to curl was printed to help figure out which option it was being passed that didn't work.
2) Potentially compatibility with libcurl could be checked upon installation to warn the user.
