[tex-live] ulqda and Digest::SHA(1)

[Norbert Preining]

Hi Ivan,

thanks for your work on ulqda. Recently a bug was reported to
the Ubuntu bug tracker, but it is the same in many other
distributions is my guess:

And that is true, it calls
	use Digest::SHA1 ...
which is not available in at least Debian and Ubuntu, but has been
replaced by Digest::SHA.

I would suggest adding instead the following code to the
script which makes it run with both SHA1 and SHA:
----
eval { require Digest::SHA1; };
if ($@) {
  require Digest::SHA;
  Digest::SHA->import(qw(sha1 sha1_hex sha1_base64));
  print "loadins SHA...\n";
} else {
  Digest::SHA1->import(qw(sha1 sha1_hex sha1_base64));
}
----

Thanks for considering this item.

Best wishes

Norbert
