Contao 3.5.0 and FreeBSD 10.1

hello,

i have apache 2.4 installed and under /usr/local/www the contao-3.5.0 -folder
and i have a Alias for contao so that i can access via browser http://localhost/contao/contao/install.php
but nobody told me that i had to install php56-session and php56-ftp.
are there any other modules which i should install with f.e.: "pkg install php56-session" in freebsd.

and now to the install.php -part:
FTP hostname
Relative path to Contao directory (e.g. httpdocs/)
FTP username
FTP password
Secure connection
Connect via FTP-SSL
FTP port

hostname is mywebserver-ip 192.168.0.104
relative path - i dont know
username is urbanks
password ...
port is 21

can somebody help me what i should enter in relative path?
and can somebody help me which modules i should install besides php56-session and php56-ftp -modules??
thank you a lot! somebody experiences with installing contao to freebsd?
