usd @20.05_2+docs+examples+ptex+python+tutorials conflicts with spidermonkey @1.7.0_8

They both try to install a libjs.dylib library:

This conflict should either be marked, or fixed. (Note that being unable to install usd blocks installation of blender for me)

I'll do some investigating to see whether the versions of libjs are different between USD and spidermonkey. If it turns out that the versions of libjs are the same, then I'll see whether I can add a check during the destroot phase to first try to detect whether libjs.dylib already exists, and if so, have USD prevent attempting to install libjs.dylib.

I have reported the issue upstream: ​https://github.com/PixarAnimationStudios/USD/issues/1615

[jasonliu-- (Jason Liu)]

I will mark the two ports as conflicting, until a permanent fix is implemented upstream.

Replying to jasonliu--:

I will mark the two ports as conflicting, until a permanent fix is implemented upstream.
