Ah, if I am understaning the script right, then there is a whole directory, $PVSW_ROOT/lib64/, that doesn't exist and therefore all those lib files it wants to register don't exist either.
(Hang on, my brain is actually expanding, I can feel it!)
So I searched the whole file system for a folder called lib64. I found several folders called that, one had a file that was a symbolic link to a file called libpseucjp.so.3, I don't know if this is actually the file that the script is looking for or not (dso_register libpseucjp.so $PS_VER). Searching libpseucjp.so returned two instances of the same symbolic link, and two instances of a file called libpseucjp.so.3.10.014.000
(one fault with the search program in Fedora is that it doesn't tell me the path to the file it found, so I have no idea where these files are.)
So, if I had to hazzard a guess, there is something wrong with the pointer or the path.Remembering something Ann told me, I checked the script in the section covering the export options. Although I didn't get any errors from the script, the output from export does not seem to set the variables, which maybe why the scrip can not find the /lib64 folder. I am going to reboot, just to see if it makes a difference, and rerun postinstall.sh
