hpmachining [1] filed a deletion request for v8-6.8 [2]: I added this package because it was needed at one time to build cbang- git and camotics-git. I have updated the 2 packages to use the latest v8 from the v8-r package. Also, it has build errors with the latest icu and I don't see any reason to attempt to fix it.
