However, I have introduced another problem while adding the fixes. As
soon as I had done that and restarted GAP it complained "autpgrp is
older than version 1.1, please download new version from ..."

So I did that, deleted the old pkg/autpgrp directory and untarred the
new pkg/autpgrp directory, and restarted GAP to get the message:

Syntax error: warning: unbound global variable in
/home/local/research/gap/gap\
4r3/pkg/autpgrp/gap/autos.gi line 407
SetIsGroupOfAutomorphismsFiniteGroup(A,true)

I guess you are using version 1.12 of autpgrp.

That version seems to be meant for use with GAP4.4, which, in as far
as I know, is not out yet:

if IsFinite(G) and CompareVersionNumbers( VERSION, "4.4" ) then
SetIsGroupOfAutomorphismsFiniteGroup(A,true);
fi;

version 1.11 does not have the problem.

My best guess is that the warning is a nuisance, but harmless.
The authors, whom I believe read this site, could confirm or deny this
and maybe do something to suppress the warning in older (that is
already released) versions of GAP.

Sincerely,

Luc.
