Okay, I'll get a thread over in the VPS forums by the end of the day.
Could you put PM the configure command (available from phpinfo()

of your system, then I can make sure php has the features you have right now, or at least the majority of them.
Once you get the hang of compiling from source it's pretty much the same, apart from when you get to the odd ones such as qmail, but that's for an email server.
