No worries…

I'll check things more thoroughly, I've left these in there, because otherwise the formula wouldn't install, I'll dig deeper to find out what might be going.

What I noticed is that `extend/ENV/std.rb` and `extend/ENV/super.rb` set `PKG_CONFIG_LIBDIR` whereas `build.rb` and `extend/ENV/super.rb` set `PKG_CONFIG_PATH`. My experiments with the formula led me to the above version.

Down the rabbit hole, to find a better / cleaner solution… :smile:
