Comment:
Both of these should already be available... And 

- you don't want to depend on a specific revision of a package from another template, since they can get updated independently from each other
- you shouldn't specify versions in `hostmakedepends` or `depends`. The versions that will be used will be the ones listed in the templates for each package, so they don't affect anything besides possibly breaking a build.
