Ok, but since we continue either way in text mode we have to load the
tlpdb in any case ... right?

I see that point and will try to find a solution for that. It is not
that trivial since the install-tl script can be used for many other
things, too.

Yes, probably. So what you want is that if you ask 
	install-tl -gui
and the gui cannot be loaded, then
	1) give a warning message that we drop into text mode
	2) then start loading the tlpdb
this way you could cancel the loading and first reinstall missing 
perl-tk, and then restart, without the need to download the tlpdb two
times, the first time completely useless.

Did I got it right this time?

Uhhh, maybe, but the messages would scroll by *very* fast.

I will see if I can add a temporary window that pops up that informs
users that the tlpdb is being loaded and that it might take some time.

In tlmgr we have that, but in install-tl I have to see if it fits in.

I will try.

Best wishes
