I finally realized that there are many parts here. I had cross-compiled rasterbar-libtorrent as a shared object. It uses boost. I was able to use the test client to make sure this worked. I ported Python to my mipsel-linux platform. I had to fight with some packages but it all appears to be working ok. I was able to build the deluge package and take the .egg (and built files) over to my target. This appeared to install ok. After changing some paths, I was able to run "deluge". It will serve the web pages.
Now came the interesting part. Deluged needed the python extensioned versions of the rasterbar-libtorrent libraries. I found how to build those and installed that on the target. I started getting unresolved externals for boost (mangled name items). I found that I needed to do the same for Boost and link the python bound boost libs to the libtorrent SO. I then put that on target hardware (with other headaches of gcc/g++ link issues). Deluged now runs. However, while starting up it is causing an assertion failure in the destructor of disk_io_thread. It appears the disk_io_thread object is being destroyed but was not notified cleanly. My guess is this is an innocent bystander and the real issue is something else went wrong and the object happened to be destroyed prematurely as the disk_io_thread should stay alive for the life of execution.

After running strace I realized that the libtorrent library was trying to make a system call (epoll) that my kernel was not configured with. After changing the bjam config script to disable epoll I am able to run deluge (web ui) and deluged (the daemon). These are successfully running on a little endian MIPS processor (199Mhz I think). It appears to be doing a pretty good job. Once in the web UI under preferences, I set the template to AJAX and the Theme to Classic. It is still pretty responsive and looks good.
