Very cool, I forked this, changed the namespace if you want to use it today (old spago):

  with record-vta =
    { repo = "https://github.com/i-am-the-slime/purescript-record.git"
    , version = "bf281d7cd6a91f58c2b09e419c735646b124dbcc"
    , dependencies = ["functions", "prelude", "unsafe-coerce"]
    }

Then import as RecordVTA.Builder or whatever.
