Alpine Linux - can't build libtorrent, missing linux/netlink.h

I'm trying to compile [libtorrent](https://github.com/rakshasa/libtorrent) on Alpine Linux. autogen and configure work fine but after invoking make it fails with the following message: local_addr.cc:45:10: fatal error: linux/netlink.h: No such file or directory I looked in /usr/include and found only netlink/netlink.h. However the next include in the source file is rtnetlink.h which doesn't exist. Is this due to a missing dependency or perhaps a problem related to glibc/musl? How do you build libtorrent/rtorrent under Alpine Linux? I am aware there is an rtorrent package for Alpine but would rather prefer to build it myself, so I can customize the build options. These are the packages I installed prior to my build attempt: * autoconf * automake * libtool * pkgconfig * ncurses-dev * zlib-dev * libsigc++-dev * libcurl * curl-dev * libnl-dev
