I think you may have missed the point of what Albrecht was saying; you need at least 1.3.4, but 1.3.4 or 1.3.5 (or the 1.3.6 rc) would work *if* you compile them with the enhanced ABI selected.

By default, all 1.3.x variants build with the baseline 1.3 ABI, so waiting for 1.3.6 will not change anything, it will still default to the 1.3 ABI.

If you want the extended ABI, you need to pull a recent variant, say 1.3.5, and then configure it with:

./configure --with-abiversion=10305

Then make as usual.

IIRC the equivalent cmake symbol is OPTION_ABI_VERSION=10306
