Joe,
I think it would have to be custom-written, I'm afraid. The reason is that the script needs to know how the HTMl code on each of the sites is written in order to know where to find the job data in the HTML.
If you visit each of the job sites yourself and look at the HTML source code, you'll see that each one is different. The "screen scraper" program will need to know where to look in each page to find things like job title, salary, location etc., which will be different in each case. Hence it will need to be custom-written.
That said, a Perl program with LWP::Useragent library and a few regular expressions will suffice, so long as there are no login/registration procedures etc. that need to be dealt with.
