[oe] [meta-ruby] problems building Gem that contains C code

[Michaël Burtin]

Hi,

We (at Voxtok Technologies) have written a bbclass to handle Gem
compilation that we use to run rails applications on ARM platform.
We exposed the class (together with ruby recipe and a collection of gem
recipes) as an external layer in a Github repository [1].
Unfortunately we didn't find enough time to upstream the patches as some
part of the recipes might need to be rewritten (e.g. the ruby "make
install-cross" related changes) but it seems stable enough to be shared.
This should allow you to install gem in your image as well as installing
gems at runtime, with native extension, supposing your image contains the
dev libraries and tools.

Regards,
Michaël
