To put it briefly: if you install a binary module (i.e. containing C code to be compiled) with PPM, then you'll get a binary version (i.e. complete of compiled binaries suitable for your architecture & current perl). In any case, you should not "browse this module" - unless you're curious about its implementation, that is. You installed it, then you can read its documentation with perldoc and use it straight out of the box: did you try doing so?
