Thank you for your response. Yes, by default gentoo _always_ builds from source, and rolling back past last good ruby did not help. By using a very simple program that had lots of the “includes” from the original program I had problems with, I traced it to a “bad” “include gtk2” line. Upgrading ‘ruby-gtk2’ solved the segmentation fault problem I was having. ---
