Projects can contain internal relative symlinks and work fine with go get.
(example: https://github.com/valyala/ybc)

However, the current file handling code skips symlinks when copying - breaking otherwise fine working go-getable Go packages.

I think I have a small patch to make it work, but those knowing github.com/constabulary/gb and how it's vendored into gvt could probably make a more general patch.
