[DRE-maint] Bug#1078643: rubygems: tries to access Internet during build

retitle 1078643 rubygems: tries to access Internet during build
severity 1078643 serious
thanks

Sorry, I miscategorized the bug, as this was not really a "will ftbfs in trixie"
but "tries to access Internet during build" instead.

Such category of bugs was already considered RC by itself since a long time.

Thanks.
