For SPARC systems :
pkgadd -d http://opencsw.ma.eurocopter.corp/opencsw/pkgutil-sparc.pkg
Or for x86 systems :
pkgadd -d http://opencsw.ma.eurocopter.corp/opencsw/pkgutil-i386.pkg
Uncomment the file /etc/opt/csw/pkgutil.conf accordingly to connect to the local mirror :
mirror=http://opencsw.ma.eurocopter.corp/opencsw/stable
/opt/csw/bin/pkgutil -U
Now you can install any OpenCSW package. For example, to install vim :
/opt/csw/bin/pkgutil -a vim /opt/csw/bin/pkgutil -y -i vim /opt/csw/bin/vim
