in thread Perl5.26 installing Tk module manually

WARNING: The sqrt and ** (pow) overloading is buggy on ActivePerl. (See the README file.)

Ooops ... you shouldn't be getting that warning. (Now fixed on github.)

I used the wizard to install perl-5.28.1 from the AS msi. I'm still having trouble getting anywhere - maybe there's something in the registry, from a previous installation that's causing problems.
I've pretty much lost interest in persevering with it.

Having added my gcc-4.7.0 compiler and dmake to my path, here's what I get when I try a manual build of Math::LongDouble:
C:\sisyphusion\Math-LongDouble-0.22>perl Makefile.PL WARNING: The sqrt and ** (pow) overloading is buggy on ActivePerl. (See the README file.) Checking if your kit is complete... Looks good ...

I don't understand any of that.
I don't know what or where the "uninstalled Perl" is.
The directory \_64\active~1.28\lib does not exist AFAICT.
I don't understand the direction to "please-run-the-install-script".

Also, in their perl/site/lib/ActivePerl/Config.pm, there's a sub _warn that begins:
sub _warn { my($msg) = @_; unless (-t STDOUT) { print "\n$msg\n"; return; } require Win32::Console; .....
If AS is going to conditionally call Win32::Console, it's probably a good idea that they include Win32::Console in their distribution. (You can pass that suggestion on to them if you like.)
My first attempts at using the cpan utility resulted simply in the announcement that Win32::Console could not be found, and should be installed.
I speculate that _warn() had been called because dmake could not be found in my path ... but that useful piece of information never made it to the screen because -t STDOUT was "True" && Win32::Console was nowhere to be found.

Cheers,
