We are running on Ubuntu 14.04, with Gitlab 9.3.7, which works fine. We are trying to update to the latest security patch of Gitlab v9.3.8, but it gives us this error:
Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

--------------------
I've tried adding ruby-dev and ruby2.3-dev as we are using Ruby 2.3. No changes in the update. As this is a fairly recent patch, Gitlab has no further information on their site, and the installation instructions for re2 have not helped.
