To my knowledge no.

Steps to reproduce

1. Update the carapace template with the latest version and checksum.
2. Try to build the package.

After further experimentation :-
The issue seems to be setting of custom GOPATH to be inside the wrksrc directory.

NOTE: Not a go developer I have never written go or understood how go build system works.
I would love to know why this happens as well.
