I’m attempting to install v6.1 on a newer Linux. makelocalrc and perhaps other parts of the installation failed because the glibc version (2.7) is apparently newer than what is supported. Is there some updated install script for older pgi versions? Is there a manual fix that can be done, or is this hopeless?
You can probably manually edit makelocalrc to accept newer glibc. Look for glibc= in makelocalrc (it is normally in get_glibc_version) and add glibc=2.7* as another case to it.
