Hello

I have a problem when i try to configure an installation with a Gemfile.custom

the setup script for some reason is using the address
git://github.com/omniauth/omniauth-saml.git to get data, but my server is behind a proxy, i configured git —global with the right proxy configuration, but only https clones/fetches work, is it possible to change the script to use https instead of git://

is it possible to do this manually somewhere in the installation files?

Yes you can override the protocol used by git and force using https:

git config --global url.https://github.com/.insteadOf git://github.com/

Best,
Oliver
