Eduardo,

I think one issue is --sysroot is using the host path that might be 
contributing to the Arch mismatch message. I have a patch that I have 
not submitted, yet.

Regarding the .debug, you might need to add

FILE_${PN}-dbg += 
"/usr/lib/ruby/gems/2.2.0/gems/msgpack-0.5.11/lib/msgpack/.debug"


It you could try the patch I have attached and let me know if it helps.

regards,
Armin

Subject: [PATCH] ruby: fix  sysroot issue

The --sysroot=/ is set to the host path, when using ruby on a target
machine.

This only becomes a problem with compiling native support using gems.
