It might depend on your definition of a trojan (trojan horse program).
A trojan on linux is rare. A virus on linux is rare.
A worm on linux is slightly more common than either a trojan or a virus
but its still rarely seen by anyone.

On the other hand... scripted probes looking for un-patched exploits is
extremely common. If one is found then manually using it to get into a
machine is common enough to have been seen by many admins. That is often
used to install a backdoor program or owning program (such as a
rootkit). In cases such as that I wouldnt really call it a trojan since
Ive never seen it use a program masquerading as a good thing to get the
machine owner to run it.
