These are some dummy scripts to find which gems that GitLab is using, are missing from Fedora repositories.

On a Fedora machine, clone the repository, cd into it and run:

sudo yum install python2 python-bugzilla python-pkgwat-api
chmod +x run.sh
./run.sh

Note that it could take some time because it queries both Fedora's repos and rubygems.org.

Gitlab runtime gems  :  145
Gems in Fedora repos :  386
Common gems          :  69
To be packaged       :  76
Pending review in BZ :  11
When BZ go in repos  :  65
