Looks like you downloaded 3.0, instead of 3.0.1. Just change the download to https://github.com/NagiosEnterprises/nr ... 0.1.tar.gz. The instructions say 3.0. I'm about to go figure out why. 3.0.1 was released in early September.

You're trying to execute a script which is on a file system mounted with the noexec option:

You can run the compilation from another location. I like to use /var/tmp personally on Debian installs. Just note in the thread where you put it, so we can refer to it properly if there are issues.

getnameinfo is simply stating that it could not resolve a dns name to an IP. Is your dns server accessible? As for the 5666...just try running the command without the 5666.

When you say you are running npre, is /usr/local/nagios/libexec/check_nrpe -H localhost the command you are using? If not, could you post the command?
