This was exactly the problem. Referring to the suexec documentation, it says to 
not use it unless you want it, and to disable it by moving the binary. So I ran 
'cd /usr/sbin/ &&  mv suexec suexec.disabled`, restarted apache, and everything 
started working as expected.

I'd suggest improving the error message to mention suexec rather than just 
'Premature end of script headers'.

Thanks everyone!
