I have a problem while installing a gem for the debugging with eclipse.
I'm on mandriva 2009, here is the error message:

[root@localhost lolveley]# gem install ruby-debug

ERROR:  Error installing ruby-debug:

do you know from where it is coming?

You need the Ruby header files:
sudo urpmi ruby-dev

well, it doesn't work.
not exactly.

indeed, I have the package ruby-devel in the package manager, but with
the version 1.8.xx, but what I want is a ruby-debug 1.9.xx, and with
this ruby-debug comes ruby-devel-1.9.xx (I suppose actually).

but impossible to find ruby-devel-1.9.xx ...

thanks anyway, another idea?

stop searching!

it works!
I kept the ruby-devel-1.8.xx.rpm and installed the gem ruby-debug, and
made some tests : all works fine.

thank you,
