So in general, packages use environment variables to find the 
absolute paths of their dependencies in the store?

In a package definition, are those dependency paths always set 
using wrap-program? Are search-paths, native-search-paths, and 
setenv also used to set those environment variables or are those 
used for something else?

So how else can packages propagate run-time dependencies besides 
environment variables?
