This is a bug in rpm's handling of %pretrans dependencies. I'll try to 
get it fixed tomorrow, BUT this also does point out a problem in the 

%pretrans scripts can almost never in real life be /bin/sh scripts, 
because on initial installation, at the point where %pretrans scripts 
get executed there is no shell! Or anything else for that matter. The 
only kind of %pretrans script that always work are ones using the 
embedded Lua interpreter, ie '%pretrans -p <lua>'. External interpreters 
in %pretrans are /supposed/ to work in upgrade scenarios (barring this 
bug, duh), but as in practise you can never guarantee a package is only 
ever applied as an update on an already running system, %pretrans 
scriptlets using /bin/sh or such external interpreter are not usable.
