I did almost the exact thing a couple of brews ago. I made the starter as per normal the next day, when the brew day came I pitched it on in and I ended up with a nice vigorous ferment.
Sure leaving it out overnight, or warm shipping, any of these things are going to begin to degrade viability of the yeast, but that's what is great about a starter, you're building back up the yeast count (and increasing it over the levels provided by the manufacturer). Heck, with a good starter I've taken Wyeast smack packs a year past their expiration date and brought them back to usable form.
So yeah, you're fine. Brew on!
