You did the job at least for lua ;-) As far as I remember, I prepared some of the 2.12-* uploads during DebConf'07, and a ruby policy was pending. That's why I didn't apply any modification to the ruby package until now. I've got to check whether such a policy is available now… I hope the tweak mentioned in gv_ruby.3 will suit your needs until I do what's needed. I'll probably include further bindings modifications into the 2.16-* uploads to experimental (2.16-2 is there already). I've got some C++ linking errors to solve at the same time. > (SWIG just provides low-level interface with script languages. > Ideally, a higher-level interface should be built on this interface > and that interface should be shipped as /usr/lib/ruby/1.8/gv.rb > instead of /usr/lib/ruby/1.8/gv.so.

Thanks for the comments and the reminder (I must confess I forgot a bit about the ruby binding). Cheers, -- Cyril Brulebois
