You can install only needed packages. In this case you must download and install clip_dev.tgz It contains Clip compiler itself, some utils and standard debugger. For installing this package you need to download it from ftp server and unpack in convenient directory.
Now, if you want a local installation, you needing to set CLIPROOT environment variable (for example: export CLIPROOT=~/cliproot) and start ./configure from where you unpack your file.
If you want to make system-wide installation start ./configure -r (that key means "release"; other keys you can get by ./configure -h).
After this run "make" and (with appropriate rights) "make install".
For correct working you are still needing to add CLIPROOT in your .profile as described above.
Each other clip_* package can be installed by the same way.
