one suggestion I have, since I noticed that your build script to build from source seems to check out master, is to pin to a specific version of v8 - that makes it a bit easier than trying to keep up with a moving target :)
Even internally I use brew'd, apt-get'd and nuget'd version for build. I want that my plugin compile faster ;)
The v8 build script is kept for advanced user and potential contributors ;)
just checked, nuget is 6.4.388.11, brew is 5.1.281.47 - do your users a favor, and get this updated asap.
plv8 uses 6.4.388.40, which is fairly safe, but requires a build from source.
FYI, my email is in my profile, if you want to move this off of hn.
Where can I find your email!?
