There are a few dependency cycles that may have to be build in stages 
with bootstrap packages. First build package "one" without dependency on 
"two", then build "two" with dependency on "one", then rebuild "one", 
this time with dependency on "two". Maybe rebuild "two" as well. These 
bootstrap PKGBUILDs do not exist in the archlinux sources, so you have 
to create them on your own.
