Incorrect package names for ruby-* gems

[jonhoo]

pacgem ruby-progressbar installs a package named ruby-progressbar, and not ruby-ruby-progressbar as dictated by the Arch Gem package guidelines. This makes adding dependency on pacgem-installed packages harder, and leads to potential conflicts (i.e. there is both a progressbar and a ruby-progressbar gem, and pacgem would compile them to the same package name).

I am not sure about this. Should we maybe remove the normalization alltogether?

"#{ruby_package}-#{gemname.downcase.sub(/^ruby-/, '').tr('_', '-')}"

Like downcase etc. Because this can in principle also lead to clashes.

I think at least the downcasing should be preserved. From the Arch packaging standards on package naming

Package names should consist of alphanumeric characters only; all letters should be lowercase.

Whether it makes sense to also convert underscores to dashes, I'm not sure. Judging from the Gem naming standard, _ and - have different semantic meanings, and so you could, in theory, have different packages differing only in their use of _ and -. Thus, it might be best if _'s aren't translated. I'm not sure if this breaks Arch dependencies though..
