how to install desired port

[Sadashiv Kulthe]

Hello,

thank you for reply.
I got now syslog as well as sysctl  is there but they have problem... I think

Can you tell what is the problem with my server using following output.
I can not use make or install a port on it.

-bash-2.05b# cd /usr/ports/
-bash-2.05b# cd  graphics/png
-bash: cd: cd: No such file or directory
-bash-2.05b# make
/usr/sbin/sysctl: not found
"/usr/ports/Mk/bsd.port.subdir.mk", line 60: warning:
"/usr/sbin/sysctl -n kern.osreldate" returned non-zero status
===> accessibility
===> accessibility/at-spi
"/usr/ports/Mk/bsd.port.mk", line 2039: Malformed conditional

/usr/sbin/sysctl: not found
"/usr/ports/Mk/bsd.port.mk", line 2596: warning: "/usr/sbin/sysctl -n

-bash-2.05b#

Also 
following is the output of whereis and apropos

-bash-2.05b# whereis sysctl
Warning: couldn't stat file /usr/X11R6/man!
sysctl: /usr/share/man/man8/sysctl.8.gz
