creating a gem which installs files outside /usr/lib/ruby

[Stefano Crocco]

I want to create a gem for an application written using the ruby KDE bindings.
It's the first time I create a gem, but I think I more or less understand what
I should do. The only issue I'm having is that, KDE expects to find some files
(in particular, the program icon and the program .desktop file) in some
specific directory (namely, in one of the directories listed in the KDEDIRS
environment variables, which usually means something like /usr/, /usr/local
and /usr/kde). Is there a way to tell rubygems to install something outside
the /usr/lib/ruby directory tree? According to the documentation at
http://docs.rubygems.org, rubygems can be told to install binaries in
/usr/bin, but there's nothing about doing the same for other kind of files (at
least, I couldn't find it), so I guess the answer is no.

By the way, the documentation at http://docs.rubygems.org seems quite outdated
(at least, the Gemspec reference page says it's last been generated in 2005).
Does anybody know whether more recent documentation can be found?

Thanks in advance
