OpenSUSE: Getting to work the ruby script to login into dyndns.com automatically every week.

So I remember for the next time:
zypper install ruby
zypper install ruby-devel
zypper install gcc
zypper install gcc-c++
If you don’t install all these, them the gem will fail with errors like this:
ERROR: Failed to build gem native extension.
/usr/lib64/ruby/1.9.1/mkmf.rb:381:in `try_do': The compiler failed to generate an executable file. (RuntimeError)
You have to install development tools first.
What helps a lot for sorting out the above error messages is the Zypper Cheat Sheet (PDF).
But zypper was not enough as still it failed:
gem install mechanize
will eventually end with:
No such file or directory - getcwd
That was solved by running these two:
gem update
gem update --system
So I could install mechanize:
gem install mechanize
Now this works:

Well, great, but dyndns has discontinued its free service some time ago, hasn’t it?
