Seeing this, I downloaded igraph from current git master, and found that I
still needed to make the following change:
leopardi@catawba:~/sync/src-downloaded/igraph/git/igraph$ git diff -b
diff --git a/interfaces/python/src/graphobject.c
b/interfaces/python/src/graphobject.c

Are you (Tamas) planning
commit/38b76ddee419053cbb8b3428d32f22adb6bcf483<https://github.com/igraph/igraph/commit/38b76ddee419053cbb8b3428d32f22adb6bcf483>to
master soon, or should I just continue to use my patched version?
