# to install brew, as user execute this:

===== Installing =====
Don't do it like this - not working so far for me.
<code>
sudo su -
cd /Users/chorn/pcpserv/pcp/pcp-6.1.1/build/tar
    # ./preinstall
    
preinstall needs a small fix:  on line 172:
-      $PCP_ETC_DIR/pcp/indom.config \
+      $PCP_ETC_DIR/pcp/indom.config; \ 
   
    # here=`pwd`
    # ( cd /; tar xpf $here/pcp-*-[0-9]*.tar.gz )

etc/init.d/pcp: Cannot extract through symlink etc/init.d/pcp
etc/init.d/pmcd: Cannot extract through symlink etc/init.d/pmcd
etc/init.d/pmie: Cannot extract through symlink etc/init.d/pmie
etc/init.d/pmlogger: Cannot extract through symlink etc/init.d/pmlogger
etc/init.d/pmproxy: Cannot extract through symlink etc/init.d/pmproxy

etc/pcp.env: Cannot extract through symlink etc/pcp.env
etc/pcp/bind2/bind2.conf: Cannot extract through symlink etc/pcp/bind2/bind2.conf

=> This does not succeed, as /etc and /var are symlinks. 

Maybe this:
(cd /private;     tar xpf $here/pcp-*-[0-9]*.tar.gz )
    
    # ./postinstall
