yarn: default to an older nodejs on 10.6

[mojca (Mojca Miklavec)]

nodejs6 only seems to work on 10.7 and later (see also #53165 and many other tickets).

Based on comments in the portfiles it seems that nodejs4 and 5 require at least 10.6 and nodejs requires at least 10.7. It would be nice to fallback to an older version of nodejs (perhaps version 5) on < 10.7.

Btw: is the isomarcte's email in Yarn misspelled?

I've opened a PR on Github that attempts to fix this issue: ​https://github.com/macports/macports-ports/pull/127

yarn: use older NodeJS on <= 10.6, typo in email

Fix a typo in maintainer's email

Node JS 6 cannot be installed on Mac OS X 10.6 (Snow Leopard)
and earlier. This change checks the major OS version and uses
Node JS version 4 when appropriate.

Closes: #53166

Thanks for the fix!

Quick question: the dependency is set with depends_run, but commit ​5b6de0c7 changes the pre-10.7 code to use depends_lib-replace. Does depends_run-replace not exist?

I'm sorry, I suspect it was a copy-and-paste error. Thanks a lot for noticing.
