The ${prefix} is not applicable on this platform for perl and python. Those locations must be in /usr/bin and are managed by the Operating System vendor not by customers. The change is wrapped in an IF so is only applicable to NonStop.

There is a temporary failure in the vendor supplied rm. The cause we never disclosed to my team. Honestly, it created a large amount of angst that should be gone but there are still old OS versions that have this issue. This is as much as we know.

This came from another team. We can't currently use config.autogen anyway on the platform - this came from the prior attempt at porting. By misdetect I mean just that, however. We do not get good values.

Another team is current working on the PTHREAD implementation and wanted this. I think what happened was that we have non-pthread requirements under development. I can remove this.
