Not sure if you should if you can't find it. It's rather buggy and problematic still, so it's best for those that can help themselves.
However, I'll go ahead and tell you, and let you decide from here. Use the private pack code "152wgt" to get the version with gregtech, and "152ngt" to get it without GT. They currently recommend using version 0.2 as there are some issues getting 0.3 and 0.4 to work for many people.
