When trying to install Graphicsmagick binaries to FreeBSD using
sudo pkg install GraphicsMagick
via SSH shell, I get this error message:
/usr/local/lib/libpkg.so.3: Undefined symbol "openat"
What is wrong?
You need to update FreeBSD. You're trying to use a port too current for the system you are running. You can either perform a binary upgrade, or you can update the source and build the kernel & world.
