Only "local" directories, files, and sym-links are changed, not the  
files the sym-links point to (although I'm not sure whether HFS+  
supports this feature). Although I'd prefer group admin, wheel is so  
anonymous ...

2755 for directories might be a better choice: then automatically the  
new contents in such a directory would be owned by the owners of this  
directory. No "post-fixing" would be necessary.
A problem could arise from executable files (Ruby, Perl, and other  
scripts, for example in ConTeXt or XeTeX): they would lose this  
attribute.

You could use '-exec chmod g-w {}' which would take away the write  
permission from members of the group. It would work on both, file and  
directory, at once. It could be expanded to '-exec chmod go-w {}' to  
take away write permission from group members and the rest of the  
world. The permission to execute a file (script) would not be changed.

Since you tell find where to start, the danger of damage is greatly  
reduced ...

I think TeX Live has no idea of "personal set-up." So part of its  
installation is "public property." Could be that PK files are also  
built in this area ...

With Capitalism man exploits man. With communism it's the exact  
opposite.
