I have managed to get the nrpe daemon running on hpux on itanium and PA risc.
I never managed to get ssl to work. So from the nagios server I have to use the -n (noSSL) option with nrpe.
We used precompiled binarys for both nrpe daemon and the nrpe pluggins
We had the nrpe daemon for hpux-Itanium on a cd, I dont know where it came from i think it was part of "HP's Internet Express repository" it may have come from here mayoxide.com/naghpux/
If you search around HP's forums Im sure someone will help you out.

The PA_RISC nrpe daemon can be downloaded from here
to start the nrpe daemon you have to run a configure script
hop this helps
