Error while trying to build RPM from .gem and .spec

RPM build errors:

I created a tarball with a .gem file in it which is called "reedb-0.11.gem" and it seems to be unpacking it correctly.
What I don't understand is how it finds the .spec but doesn't correctly copy the .gem to the directory it needs to be in.

Not sure if this is a bug with your code. But maybe you can help me? Thanks

Can you paste the exact command and full output? I'd also like to see a tar tf on the tarball and a copy of the spec if you can share that.
