Packer is a tool for building cross-platform Starpacks with Tcllib included. It takes as input the content of a Git repository, e.g., on GitHub. The only assumption made about the source repository is that it includes a lib/ directory into which Tcllib will be copied. Packer builds Tclssg by default (for which it was developed). It can be customized by overriding select default options; see the file build.tcl in the repository for an example of how it can be done.
