I'm now using Ubuntu i.e. no Windoze, for any perl development and found your base strategy to work reasonably well ... until I came to install Devel::ptkdb.

What fun and games I had trying to first identify, then locate and finally install Tk and all the dependencies on my laptop.

When I came to install on the desktop, I discovered the perl-tk package - which, as does as it says on the tin, and delivers it [Tk] at the press of a button - what luxury - thus considerably simplifying the CPAN installation of Devel::ptkdb.

The conclusion is, like a lot of things, to abide by the spirit of the KISS acronym - if it's already been made easier (by being pre-built & packaged) then use it (someone else has already been thro' the pain & it would be rude to ignore their effort - .oO(If only there were ways to recognise it)), otherwise use the CPAN approach.

Just my 2 pen'orth
