When using

require Alien::wxWidgets;

Perl raised an error:

Can't locate Module/Pluggable.pm in @INC (you may need to install the Module::Pluggable module)

and as a consequence the following code in wx:

eval { require Alien::wxWidgets };
our $has_alien = $@ ? 0 : 1;

resulted in $has_alien = 0.

It seems that p5-module-pluggable has been removed from Perl core (​https://rt.perl.org/Public/Bug/Display.html?id=116491).

I upgraded p5-module-pluggable in r123776 and fixed p5-alien-wxwidgets in r123777.

I'm still getting:

Possible precedence issue with control flow operator at /opt/local/lib/perl5/vendor_perl/5.20/darwin-thread-multi-2level/Alien/wxWidgets/Utility.pm line 77.

and

'WX' is not a known MakeMaker parameter name.

but wx at least compiles now. (Some tests fail and I get a lot of "Failed to create the clipboard (error 13: Permission denied)" warnings/errors, but well ...)

Committed in r123780.
