I think this is not correct. You want to build the analysis_server, but that
package has transitive dependencies. E.g. If the watcher package gets a fix, you
need to rebuild the analysis server as well ...

Conservative solution would be to depend on all dart files in dart/pkg?

You can depend on pkg/pkg_files.gyp and then have the stamp file as input. You
can see how pub or docgen does this

Thanks for the tips!  I *think* I got it right.

Perhaps take another look?
