How to get pcre 8.x on Ubuntu 10.04 (Linode)

I'm trying to set up Bug Genie 3.x on my Linode server, and it is complaining because I have pcre 7.8 instead of 8.x. Doing an apt-get update and upgrade doesn't help and says that I have the latest version of libpcre3. Am I supposed to install something else, or is 7.8 the latest version in the apt-get libraries right now?

I'd be comfortable building from source if someone can supply very detailed instructions, but otherwise I'd probably end up making a big mess, and would rather use apt-get anyway.

Note that this will have to work with a standard LAMP stack (apache/php), so if there's any gotchas there that anyone knows about, I'd greatly appreciate any heads up that can reduce my headaches later on.
