app-editors/ng-1.5_beta1 compiles and seems to work on amd64. The doc's aren't that great, but it appears to work; never found out how to save. It did get an $EPATCH_SOURCE error, but I assume this happens any time you try to compile from an overlay and it needs patches?
if you don't have the patch in the files dir it will fail obviously. Marked Testing in CVS Thanks
