I am guessing that you are using the repositories on the download page of the Namecoin website.

The problem is Linux Mint 17.1 is based on Ubuntu 14.04. The package in the Namecoin repository is targetted at Ubuntu 14.10. So some of the dependencies are newer than the ones you would find in Linux Mint 17.1. I don't know much about Linux Mint, but I think 17.1 is the newest version, so upgrading is not an option.

So, you could either download the Namecoin source code and build it yourself, or binaries or a repository for Ubuntu 14.04 can be created. I would provide you with the binaries or a repository myself, but it's not a good idea to trust binaries not from an official source.

The error message means that the Namecoin package from the repository requires a version of libstdc++6 that is version 4.9 or above. However, Linux Mint 17.1 only provides version 4.8.2-19ubuntu1, which (if you leave off the -19ubuntu1) you can see is less than 4.9 (4.8.2 < 4.9).

Thank you for explaining that. I kinda figured that to be the case but Im by no means a linux expert. Ill try building from source.

Oh, sorry, I only saw the 14.10 ones.

So senoird, you could use the repositories pmc linked to, but be sure to use the xUbuntu 14.04 instructions instead of xUbuntu 14.10.
