4.0.9 to 6.9 in Haxe RC2 - Buffer of undefined

We have a nodejs application coming out of Haxe code. Somewhere down at line 22000 in our JS Output we have a
`require("Buffer").Buffer`
We updated hxnodejs to 6.x. Now with our NodeJS server we are getting a "TypeError: Cannot read property 'Buffer' of undefined"

Line 4 of the JS output has
`var require = (function(r){ return function require(m) { return r[m]; } })($s.__registry__ || {});`
Commenting this out allows the server to run. It probably will error on anything requiring Buffer...but that isnt tested
