in reply to Perl5.26 installing Tk module manually

Several years ago, I switched from ActiveState to Strawberry because of the difficulty with installing Tk. I feel that AS's documentation and module management systems do offer an advantage to users with little or no knowledge of UNIX. (Until you need a module that it does not support!) Strawberry Perl is almost indistinguishable from Perl on UNIX. The disadvantage of this is that you may have to look up instructions more often. The advantage is that you can be far more confident that they will work. I recommend that you switch to Strawberry. That is probably the best solution to your immediate Tk problem. It will probably save you from similar problems in the future, without you even being aware of it.
