You must first install onto the primary computer because its installed binary files are used to run the ccm_install command when you create installation areas on other computers.
For example, on an Oracle Solaris platform, enter the following commands to use the /vol/sun/ccm72 directory for the primary installation.
root@sol# mkdir /vol/sun/ccm72
root@sol# cd /usr/local
root@sol# ln -s /vol/sun/ccm72 ccm72
root@sol# CCM_HOME=/usr/local/ccm72; export CCM_HOME
root@sol# PATH=$CCM_HOME/bin:$PATH; export PATH
root@sol# cd ccm72
root@sol# /media/ccm/unix/bin/ccm_install -x
