The package from kopsis works on the Cacko ROM as well. I have stripped the libraries (reduced size from 3.5 MB to 1.3 MB), put them into /opt/QtPalmtop instead of /usr (don't know if that's better, it's just where I put all programs) and added a dependancy on libiconv.
The resulting packages are attached for those interested.

One small problem: If you have LANG set, it doesn't work - use "LANG=C svn" then. I guess it's a problem with missing locale stuff, perhaps someone else knows a better solution?
