Modifying PATH in Leopard

Apple has (regrettably, in my opinion) changed the way to modify the bash PATH variable system-wide. The old way was to carefully edit the file /etc/profile. The new way is quite different. Suppose you have the application MyNewApplication in /usr/local and want to include the directory /usr/local/MyNewApplication/bin in the PATH. Then what you do is

• Go to directory /etc/paths.d (yes, that's a directory) and create a file called MyNewApplication
• Edit the file MyNewApplication with the directory you want to include, i. e. /usr/local/MyNewApplication/bin. If you want to include more than one path of MyNewApplication, then add more lines (one line per path)
• Restart the Terminal

I don't agree with this approach which breaks a standard UNIX feature. This is most likely to be the reason why LaTeXiT is having troubles.
