poppler and leopard - LegacySupport issues

[Riccardo Mottola]

Hi!


now that I unblocked cmake and clang-5.0, I continue installing 
dependencies for gimp2!

Poppler is on the way, I get the error below. It is already building 
with clang 5.0 and the issue appears to be LegacySupport itself.

Am I missing some other "trick" ?
