Regex File Renamer is a Mac OS X automator action that I wrote in 2007. It renames files using Perl regular expressions.

Here's a screenshot:

Recently I attempted to install the Algorithm::SVMLight perl module via CPAN onto my Ubuntu box. It did not go well. I discovered that the CPAN package doesn’t include half of what you need, and I could not find any directions anywhere about how to get it to work. That compounded with svm-light’s lack of commenting made for a fun evening.

I’m posting my experience and solution here so maybe someone else who has the same problem can use it and not have to pull their hair out like I did.
