No, I am not saying that every new module installation requires a complete Perl rebuild.
I think you can still do ">cpan install XXX".
In this thread, I saw a question like: "unable to install Tk".
AS (Active State) is saying that they can build a custom version that includes
massive packages like Tk - and that this build process will work.
If you can select the package(s) in their GUI, the build will succeed,
meaning that all dependencies will be resolved.
I don't think you have to do this for every package.
Based upon the feedback so far, it appears that my AS 5.26 custom build with Tk DID WORK.
That was the OP's question: asked and I think answered, albeit in an xy way!
