No idea what this is all about...

WARNING: PIE does not support background-image. Use @include background(linear-gradient(top, #ffffff 0%, #f5f5f5 100%)) instead.

I am also seeing this issue with 0.12.7 after installing compass-mixins using NPM. Interesting, the warning wasn't present when I installed it via Bower.

I don't suppose anyone's found a resolution to this yet have they?

[ccorcos]

I'm using bourbon now instead ;)

[ijy]

Well that's one solution at least. :)

The problem seems to stem to the Compass core library in how the background mixin is applied(?)

[indrekots]

I'm guessing this is still an ongoing issue?

[haluvibe]

Yes, I'm also experiencing this issue. Would be great to get a resolution :)

[ccorcos]

Solution is -- dont use compass!

[dankelleher]

This is still an issue - I don't think it should be closed.

[gfdesign]

I have the same issue. Has been any solution for this?

This project isn't actively maintained. We'll accept PRs to fix this however I suggest looking at a modern alternative like bourbon.io or autoprefixer.
