The only drivers that tend to cover those prism2/2.5/3 USB devices are from the linux-wlan project. You can check them out here:

An RPM is available, but I don't run an RPM distro so I don't know how well they work.
make excutes a makefile, if there is one, the usual steps in compiling something are:
tar xvzf package.tar.gz
cd package/
./configure
make
make install
Usually a package comes with an un-configured makefile that the configure script modifies so it'll specifically use whatever kind of software you've got.
