I tried brew install astroid --HEAD but apparently my branch was already up to date :-) and I got the same result.

[mtniehaus]

Looks like the MacOS "Handle" definition conflicts with the JavaScriptCore "Handle" definition. I see that's been fixed in the Webkit source:

bool isReachableFromOpaqueRoots(JSC::Handle<JSC::Unknown> handle, void*, SlotVisitor& visitor, const char** reason) final

from a later release:

https://trac.webkit.org/browser/webkit/releases/WebKitGTK/webkit-2.30.3/Source/JavaScriptCore/tools/JSDollarVM.cpp

Maybe someone can update this?
