Waldek,
Thanks very much for looking into the Motif problems.
[Apologies for slow response: I've had some other urgent tasks, deadline
today! Now done.]

I would like to install that in the current version of V16. In principle I
should work out how to get the latest poplog from the git repo and use it
to build a new version of the file my download script has been using,
copied from your website
poplog_base.tar.bz2
do you have a script that built that file using contents of github which I
could copy and use to get a new version, so that the current install file
http://www.cs.bham.ac.uk/research/projects/poplog/V16/getpoplog.sh
does not need to be rewritten?
That would be very helpful.
Otherwise I am not a github user so if you could provide commands for me to
create a new version of poplog_base.tar.bz2 I would be very grateful.
I appreciate that you have pointed out that there are remaining obscure
problems!
Aaron
