Comment (by szhorvat):

 Since this error seems to be triggered by a simple #include <iostream>,
 perhaps it should be dealt with globally instead of in a per-port manner?

 There is a chance that for igraph it was somehow triggered by the latest
 version using -D_POSIX_C_SOURCE=200809L.  But defining this symbol should
 not break #include <iostream>

 Unfortunately I can't test on 0.10.7 or 0.10.8 to investigate this in
 detail.
