Rakudo (Moar 2019.07.1): Gumbo install via zef aborts due to test failure

[jubilatious1]

Hello, your module was recommended on reddit on the thread below (bottom). However when I try to install it via zef on a recent Rakudo install (MacOS machine), the Gumbo install aborts due to test failure:

Maybe this whole issue will clear up when the next version of Rakudo is released next week, but I thought you should know. Best Regards.

Hello, you need to install the Gumbo library first. If it still fail to find it you can tell the module how to find it with PERL6_GUMBOLIB="/path/to/.dylib"

Ahhh. Thank you. Somehow I got confused between your module and @ruz 's Perl5 HTML-Gumbo module, which he describes as a P5 module that "help[s] install gumbo parser for perl modules to use."

A few installation notes:

-- 1. I tried installing Google's gumbo-parser using both HomeBrew and MacPorts, but it was only after HomeBrew installation that your P6 Gumbo module worked.

https://formulae.brew.sh/formula/gumbo-parser

mbook:~ homedir$ brew install gumbo-parser
mbook:~ homedir$ PERL6_GUMBOLIB='/opt/local/lib/libgumbo.1.dylib' zef install Gumbo

-- 2. There's a minor error in one line of your Gumbo::Parser test code. The "->" in your code has been replaced by a "." to give the working code below:

my $xmldoc = $parser.parse($xml);

-- 3. Would it be best within your README.md to include a link to Google's gumbo-parser Github repo?

https://github.com/google/gumbo-parser

-- 4. Finally, don't you want to tell the whole world about your perl6-gumbo module? Please send a pull request asking Google to update their README.md section entitled "External Bindings and other wrappers" to include your perl6-gumbo module.

https://github.com/google/gumbo-parser/blob/master/README.md

Thank you.
