Following the guidelines from
https://wiki.debian.org/Teams/Ruby/Packaging#Requesting_Sponsorship, I checked that the package builds cleanly with pbuilder. In addition to the update to the current upstream release, I fixed a couple lintian warnings (not all of them, but I checked that I did not add any new warning). Everything on Salsa CI is green.
Since this is my first contribution to the Ruby team, feel free to report anything that I might have done wrong or in an unusual way. I have very little experience with Debian packaging (and none at all with Ruby gems), so I might have missed things that could seem obvious.
If everything seems OK, I would like to get a sponsor for:
ruby-rack-proxy 0.7.2-1+nmu1
