I had fixed that then didn't save before I uploaded it...

Two build functions sounds like it would require two install functions 
(as each package would probably have to add a conflict to the other) 
which is really two PKGBUILDs.  I am not against adding this at the same 
time but I would need to be convinced with a (useful) real world example

As Xavier pointed out, I think that there would a big use of makedepends 
and overriding of depends in the individual package functions.  In fact, 
I am not sure what the depends array at the top of the PKGBUILD actually 
means with split packages...
