Installing (or actually building) Squish from source package is explained in the manual in chapter Installing from Source Packages.
froglogic provides binary (already compiled) Squish packages for a large number of platforms and configurations. These should be preferred in most cases, unless you find that they do not work for your application.
Typical reasons for building Squish from sources are:
Ensure or improved compatibility with the application that should be tested.
Other/newer version of script interpreter (Perl, Python, Ruby, Tcl) wanted.
