bittorrent upload too invasive

I am downloading the DVD, thank you for that.

My upload is up to 50+ KiB/s whille the download is around 5. The upload is 
totally killing the download bandwith.

I used trickle from the i586 repository but it complains in this way:

 /usr/bin/python: error while loading shared 
libraries: /usr/lib/trickle/trickle-overload.so: cannot open shared object 
file: No such file or directory

But the library looks ok.

$ ll /usr/lib/trickle/
total 24
-rw-r--r--  1 root root 22160 Oct  2  2003 trickle-overload.so

I even tried to put /usr/lib/trickle in ld.so.conf (I don't know if this is a 
good idea, but ldconfig -p does not show it up anyway).

$ rpm -q trickle
trickle-1.06-1mdk

Any idea?
Thanks.
