Hey there.  The OpenWRT integration is an external project.  You might be able to get better help on the GitHub page for the port.
Aside from that, did you use the openwrt package manager to install it?  It looks like a error with the linker, so if not, it may not be a package for the correct version of OpenWRT
              
We don’t build, distribute or have any of the OpenWRT packages on our site.  It’s all done by OpenWRT.  It’s best to just use their package manager to get it.
For other Platforms & OSes, please see the download page

fwiw, with rclone, i just download the correct executable for my cpu type.

so if i need, MIPS - Big Endian, i just download rclone, then chmod +x and it works.

no install script needed, no dependencies, a portable app.
