Following an off-list clarification by Dick Koch, here's what seems  
to be happening.

The problem only appears for people who have installed gwTeX using i- 
Installer, *before* installing MacTeX: during installation, the  
folder /Applications/TeX has been created by i-Installer, to hold the  
application "TeX Distribution Helper" (aka TeXDistTool.app). However,  
this folder has been created with permissions drwxr-xr-x rather than  

Now, when MacTeX is installed afterwards, it respects the original  
permissions defined by i-Installer. Which seem to explain the setting  
observed in my case and in a few others. Compare for example:

drwxrwxr-x    6 root      admin    204 Aug 24  2006 AppleScript
drwxrwxr-x   17 brunovoi  admin    578 Feb 14 09:57 Microsoft Office  
drwxr-xr-x   14 root      admin    476 Feb 13 09:14 TeX
drwxrwxr-x   51 root      admin   1734 Feb 13 09:14 Utilities
drwxrwxr-x    4 root      admin    136 Sep 29 10:56 iWork '06
