The answer is that there is, but we don't have it nor were we ever provided with it. I have only been doing this for about a year now and I've answered this question several times, you are the first to indecate any issue.
That is several users have asked about HPUX support and had been so content with the "Yes it works, install NRPE using one of *several methods." Unfortunatly for you none of them have said some thing like "I took your advice and did XYZ and it worked."
* Can be built from source.
* Can use pre-compiled HP binaryies.
* "Can not" be installed from any of yum, rpm, deb, or Linux.
Given this it may not be possible for you to succede here. NRPE is software that we can work on supporting, you should look for an HP specific solution. If you had problems with something other then Linux/yum then I could help.
