That is how SCons builders work, so should be no real problem.

the target is rebuilt if the source changes, or if the contents of the 
expanded build string changes - both of those are checked by comparing a 
hash with a saved hash.  The first word of the build action is assumed 
to be the command, and changes to that will also trigger a rebuild.
