in reply to Bootstrap Version Issues including HTML and XML libraries
You have a botched installation of HTML::Parser. Re-installing HTML::Parser will fix that problem (so long as the re-installation is done correctly).
Alternatively, if you replace your current version (3.66) of HTML/Parser.pm with version 3.26 of HTML/Parser.pm, that too should take care of that particular problem.
Better, of course, to upgrade your perl - as already suggested.
Cheers,
