Do you see the following:

I've seen this on every machine I've installed Leopard to (all Erase and Installs).

What's going on here?
 
I'm seeing it, too

What's happening is that the dynamic linker is trying to start up,
it fails, launchd does its job and tries launching it again, it fails...

Then launchd notices that it's trying to launch it a lot, and slow
things down.

The question is why is the dynamic launcher failing.
 
The fix

Run:

update_prebinding -force -root /

FWIW, the problem seems to be triggered by the first sotware update,
not the initial Leopard install.

Can you explain...what exactly is this command doing?

It's a forced update of dyld's cache. It actually runs
update_dyld_shared_cache.

Type "man update_prebinding" from Terminal for all
the gory details.

Presumably, something is corrupting the cache, and a forced
rebuild deletes and rebuilds it, eliminating the corruption.
 
Ran that command, but still got the errors.

A reboot seems to have fixed it (for now).

Anyone know why after updates in Leopard that require a reboot (like the QT update or tonights security update)....I still get this error in the Console logs?

All I have to do is reboot a second time and the message doesn't seem to come back.

It looks as if it just happens after the first reboot.

Just thought I would update this thread. It does look like this is an issue AFTER a software update....as it is still happening for me. I did run into this tech note from Apple:

http://developer.apple.com/releasenotes/DeveloperTools/RN-dyld/index.html

The interesting part is this:

#dyld shared cache
Mac OS X 10.5 no longer uses prebinding for the OS itself. Instead a “cache” file is built from commonly used dylibs. The cache is automatically rebuilt whenever one of the dylibs in the cache is updated (usually just during a Software Update). When the cache is built, the addresses of the dylibs are intentionally randomized, thus when debugging you may notice that the address of OS routines like malloc is different on every machine.

So I am thinking that this is just an issue within Leopard on the first reboot after installing a SU. And it seems to go away after another reboot.
