That might be the issue...

I haven't built for quite some time now, and I see that there were
quite a few changes to that file this year already...
It seems like a linkage issue.

I have been told that it's probably caused by building a shared

-Wl,--ignore-unresolved-symbol,environ to work around this issue.
