Perl

Back in March of 1991, I started a new job as a software developer for a very small company. From day one, I knew that Perl was an essential tool which I needed for the job. However, I needed Perl to run on an Altos Unix system which was missing the C compiler, so this was easier said than done! It turned out to be an interesting bootstrapping challenge to solve using free software, though it did require jumping through a few hoops.
