You can easily test this. Open Terminal in /Applications/Utilities. Type
You will get a list of locations. If this list contains /usr/local/bin
and /usr/texbin, then PATH is set appropriately.
Since making the latest MacTeX packages, I discovered that the process
can indeed go wrong on Leopard. I'll fix the packages in the next few
days. Here are details:
Gerben's scripts modify /etc/profile and /etc/csh.login to add the
above locations to the PATH. But in Leopard a different mechanism is
used to globally modify PATH. Namely, these scripts now call /usr/
libexec/path_helper, which adds paths listed in the file /etc/paths
(this list contains /usr/local/bin) and then adds paths listed in
files in the directory /etc/paths.d. So on Leopard we don't modify /
etc/profile and /etc/csh.login; instead we add a file to /etc/paths.d
However, it turns out that Leopard doesn't install the new /etc/
profile if the old /etc/profile has been modified. So our postinstall
script ought to call Gerben's scripts if /etc/profile is the old Tiger
