"Should I lie about my abilities and catch up on anything I've not groked" <-- that's a nono. I personally interview candidates by finding a somewhat obscure entry (e.g. awk) and asking a few questions to suss out whether or not the candidate lied about abilities.

What is your goal?

- Find some job? Then SEO-spam. Learn SCM (svn or git should take all of a few hours to learn on your own) and ecommerce (authorize.net and paypal api are easy to learn, and its a nice exercise to write your own gateway)

- Find a job that actually fits you? Do some soul searching and figure out what in particular excites you. You may find that some experiences are unnecessary (though SCM is definitely a must)

- Find a job that will actually excite you? Try hacking together your own project, or work on an open source project to build some street cred.

Alternatively, you can play the blog game (write a blog about stuff, and broadcast to HN, other forums or other blogrolls). I seem to recall a blog by a fellow WK Selph, (he wrote a few articles about high frequency trading) which he used to land a new job.
