エラーのポイント
エラーのポイントは以下の行です。この行以外はwarningかnoteです。
insertionops.cc:36:36: error: ‘const struct ext2_inode’ has no member named ‘i_dir_acl’; did you mean ‘i_file_acl’?
os << "Directory ACL: " << inode.i_dir_acl << std::endl;

修正方法（結論）
src/insertionops.cc 内のコードを以下のとおりに一箇所書き換えます。

これは Ticket としてすでに上がっていますが、まだ取り込まれていないようです。
正しくビルドできることを確認
上記の修正をした後に改めてビルドすると、無事通ることが確認できました。
