Yes, I think this is the crux. However, I think that instead of trying
to guess at alternatives, it would be best just to do nothing, except
perhaps to print a message suggesting that the user could put the
relevant files in their path. An alternative would be to let the user
set $PREFIX variables as in the configure scripts of many packages.

I think the best would probably be to just test wether the effective
uid of the process running is 0 which can be done by 'id -u'

Testers required:
A new script to untar and install the v15.6 package (now slightly
modified -- including new version number) is available.
Full instructions here:
http://www.cs.bham.ac.uk/research/poplog/v15.6/AREADME.txt
Basically these are the steps required
Fetch, make executable, and run this (if you have not previously
done so):
http://www.cs.bham.ac.uk/research/poplog/v15.6/CHECK_LINUX_FACILITIES
chmod 755 CHECK_LINUX_FACILITIES
./CHECK_LINUX_FACILITIES
That will test whehter your installation is OK for poplog, and if run
as root may insert some missing .so links to libraries in
/usr/X11R6/lib
Fetch main tar bundle (about 18MB):
http://www.cs.bham.ac.uk/research/poplog/bham-linux-poplog-v15.6.tar.gz
Fetch install script (into same directory as tar bundle)
and make it executable
http://www.cs.bham.ac.uk/research/poplog/v15.6/INSTALL_BHAM_LINUX_POPLOG
chmod 755 INSTALL_BHAM_LINUX_POPLOG
Run it without arguments to get instructions
./INSTALL_BHAM_LINUX_POPLOG
Install poplog in preferred mode in preferred directory.
Recommended command for most people:
./INSTALL_POPLOG motif bham default > install.log
Installs in /usr/local/poplog (needs root privilege
to create the directory if it does not exits)
Then look at demo scripts for testing the installation and advice
on running poplog in here:
/usr/local/poplog/v15.6/bin/demos/
Most users will find that everything works as before, except that
installation is faster and total file space required is reduced.
Not everything that was in the previous bham bundle is included.
There are still loose ends to be fixed and documentation to be
updated (lots of documenation).
Thins that used to be in $poplocal/local are now mainly in
$usepop/pop/packages
though some have been moved into system directories, e.g. to
fix bugs or extend facilities. See
http://www.cs.bham.ac.uk/research/poplog/v15.6/MOVED/
