I found that I really don't need everything in pdaXii13 full so i went for base instead. I do like rox however, but I can't get it to run.
After installing rox, rox-session and the missing dependecies gnome-vfs, dbus & dbus-glib I get the following error when I try to run rox:

/usr/apps/ROX-Filer/Linux-armv5tel/ROX-Filer: relocation error: /usr/lib/libgnomevfs-2.so.0: undefined symbol: g_thread_pool_set_sort_function

I guess there has been some version mismatch. Anyone know how to grab the right ones?

I don't have an answer for your error, but I install the following files whenever I reflash pdaxii13 akita (base) to get Rox working.
I have these on a CF card in my "core-utils" folder, specifically for installing after reflashing.
rox_2.5_armv5tel.ipk
rox-lib_1.9.15_armv5tel.ipk
rox-lib2_2.0.3_armv5tel.ipk
shared-mime-info_0.20_armv5tel.ipk
"shared-mime-info" is for getting the file icons to associate with programs that open when clicking on the icons.
I don't remember which rox-lib is absolutely necessary, but I eventually always install both of them.
Edit
One more thing you need to do is enable Rox in pdaxii13 config.

you installed libraries from the pdaxiiv2 feed without first upgrading your install to pdaxiiv2

to fix it, simply run ipkg upgrade

this would upgrade you to pdaXii13v2 (build 5.5.0). if you want to remain on build 5.4.9, then you will need to reinstall those packages you added, but from the pdaxii13 custom feed

I have the same problem
Thanks ,

Problem solved and I now have a nice pdaXii13v2 zaurus, thanks meanie. Both for your answer and all the great work you put in.
