I think this the error is very similar to that described here, and 
occurs during 'gem install'
https://github.com/rubygems/rubygems/issues/1448

which is fixed in rubygems 2.5.2, but unfortunately ruby comes with 
2.5.1. Today a new version of ruby was released, but sadly, still 2.5.1. 
So, I think this means we will need to either incorporate the patch(es) 
that fix this into the ruby package, or package rubygems alongside ruby 
somehow. Or, since there is only a problem during build time, perhaps 
clobber the gem from the ruby package with a rubygems package during 
build time. Unless you have any better ideas?

Thanks for reporting this. I'm not sure we can blame Ricardo for this. 
Rather, it is all my fault.
