Yes, that's a problem.

Some projetcs have a strict policy and remove old versions (for example because they have vulnerabilities).

So we have to regularly update our upstream links.

But we have caches on Travis/Appveyor because reconstructing those external dependencies is very costly

(see the cache directive near line 7 of https://github.com/OpenSmalltalk/opensmalltalk-vm/blob/Cog/.travis.yml).

Consequently, a green build on the CI server might well be red anywhere else...

This is a little terse for me to be sure of your meaning, but I'll take
it to mean I should submit the patch. :-)

BTW: I tested libpng-1.6.30 on the full test suite, and the set of
failing tests was the same.

Cheers,
Alistair
