For that matter, why not the following (using just the CPAN modules)?

# Almost no testing, so be warned...
perl -Mstrict -Mwarnings -MCPAN -le '
CPAN::HandleConfig->load;
CPAN::Shell::setup_output;
CPAN::Index->reload;
CPAN::HandleConfig::edit( q{prerequisites_policy follow}, );
my @tk_modules = grep { $_->id =~ m/^\bTk\b(?:::.*)?$/i; } 
    CPAN::Shell->expand( q{Module}, q{/./}, );
foreach my $mod ( @tk_modules ) {
    print qq{Attempting install of }, $mod->id;
    CPAN::Shell->install($mod);
}
'

Hope that helps.

Update: 2019-01-30 - Changed regex from /^\bTk\b/i to /^\bTk\b(?:::.*)?$/i to get only Tk and Tk::* modules.

One way is make where you specify what & how to run some command(s). Another is create a perl package (does not have to be a perl package, could be OS specific package) which will list all the Tk software as requisites. Then either run the make command or install the perl package.

Of course, nothing is stopping you to feed each module name (similar work is needed for other two methods) in a loop to the CPAN installer.
