Yes, perl is a scripting language. You may write your own scripts and do "perl xxx.pl" and be happy - no translate-compile- link as in other non-scripting languages ( i.e. c, c++, etc. ). But as you use perl more and more, you find that you may be faced with problems that have been already coded ( maybe hundreds of times by other more experienced perl programmers ); these pre-coded and tested 'solutions' reside on CPAN as 'modules'. In order to install one of these modules you must go through the perl Makefile.PL, make, make test, and make install cycle - but just once for each version of each module you want to use in your perl script. (By the way, this install operation may be made simpler by using the CPAN or CPANPLUS modules - also on CPAN ). After your modules are installed, you are back to the simple script cycle of "perl xxx.pl". Maybe if you tell us more about what you are trying to do, we can help you select a module or modules you may need and step you through the process. Don't give up! You will be rewarded.
