How to fix the error “rtorrent: symbol lookup error: rtorrent: undefined symbol”?
If you have installed rtorrent using RPMForge Repository, you are possibly seeing the error with libtorrent “0.13.2-1”. There is a conflict between the latest libtorrent and rtorrent. The easiest way, I have found to solve the error is to downgrade the libtorrent version using the same repository. Run the following to downgrade the libtorrent:
yum downgrade libtorrent
This should downgrade your libtorrent version to 0.12.9-2, which seems to work fine with rtorrent 0.8.9-2.
