One example of this is devel/apr/buildlink3.mk.  It simply checks what 
the package's options would be if it was built from scratch.  I am 
eventually going to turn this into a check of the PKG_OPTIONS of the 
installed package, but there are some other infrastructure changes that 
need to be made first having to deal with the order in which steps are 
taken.
