I commented on the linked issue, but I'll post it here too for visibility.

My guess based on the error message is that this project is incorrectly ignoring the build tags. Spew uses build tags to allow different compile time behavior for the constants in question.

In particular: bypass.go has // +build !appengine,!disableunsafe bypasssafe.go has // +build appengine disableunsafe.

The error message clearly shows that both files are incorrectly being compiled.
