Repeating the build outside of pkgsrc (using the same configure parameters) leads to the same result.

But: Compiling version 1.6.3 outside pkgsrc fails in the same way, while I was able to build this version within pkgsrc successfully (last time on 2015-09-04).

The pkgsrc package itself does not seem to have changed except the version number. Were there any other changes to the pkgsrc infrastructure that could explain this?
