There's something wrong with your LaTeX installation. First of all,
run "sudo texhash" in Terminal.app. It will output the paths of your
TeX installation. Then, make sure you've got read/execute permissions
on the directories the texhash output shows. For example: 

$ ls -l /opt/share/texmf
total 16
drwxr-xr-x    3 root  admin  102 Sep 22 10:52 doc
drwxr-xr-x    4 root  admin  136 Sep 22 10:52 dvips
-rw-r--r--    1 root  admin  729 Oct 10 10:23 ls-R
-rw-r--r--    1 root  admin    4 Feb  6  2005 release-tetex-src.txt
drwxr-xr-x    9 root  admin  306 Sep 22 10:52 texconfig
drwxr-xr-x   18 root  admin  612 Sep 22 10:52 web2c
drwxr-xr-x    5 root  admin  170 Sep 22 10:52 xdvi
 ^^^^ ^^ ^

(the important permissions are marked; additional w's are optional)
It's crucial these permission also apply to enclosed files and
folders. If yours differ, correct them recursively, then run texhash
again.

In LyX, you should probably also specify a $PATH prefix in
Preferences. Use the path you can get from "which latex".

And finally, run Edit/Bearbeiten> Reconfigure in LyX, and restart
LyX.
