Its already built for jlime Mongo Opie userland. I'll see if i can get it to build for x11 for use with the icewm userland sometime in the near future.
The Opie package of it is here:
http://mongo.jlime.com/feed/opie/sword_1.5.9-r0_arm.ipk
As for size, its tiny. Only 629k for the executable.
Cheers
