It seems you’re on a RedHat distro.
Get your RPM from http://namecoin.org/?p=download and install it.
Then run it for couple of hours to sync up.
Then buy some NMC (like 5 NMC) on Poloniex and send them to your client address.
Then use client GUI (total no brainer) to register a “d/yourdomain” (lowercase only!)
If you want I can register on your behalf and send you the private key and address, but to be safe you’d need to transfer that property to another address for which you’d need a client, so it wouldn’t really help you (and you’d also need a client to send me some NMC to pay me back :-)).
You can also install Namecoin server and use the CLI (like you would with bitcoin-core) to accomplish the same, but working with the client is much more enjoyable.
P.S. I read that blog post… I see where the Namecoin dev is coming from, but I also understand the DNSchain dev.
Some people simply cannot and don’t want to see Namecoin. If proxying it with another s/w (open source, at that) is so bad, too fxxxing bad, maybe Namecoin guys can make a better client since “everything has already been done”…
The post reminded me a little bit of the Linux fanatics from the late 90’s and early 00’s, when it kind of mattered what Linux distro one used, who looked down upon anyone who didn’t build it from kernel.org source.
Does DNSchain lower the security of Namecoin setups? Of course it does. Not everyone can make their own shoes, that’s the beauty of the centralized model. But if they don’t run DNSchain and instead run and administer their own Namecoin, would home users they be more secure? No, because they’ll mess it up even worse (if one is incompetent to install and setup DNSchain, it is very reasonable to assume they’ll do an even worse job with stand-alone Namecoin).
