This depends a bit on how you call latex here. The application itself
will not inherit the users' $PATH from their $SHELL (just request the
PATH environment variable in your application and print it somewhere,
I got just "/usr/bin:/bin/usr/sbin:/sbin"). That is restricted. So
the fact you you have customised your terminal, means squat for a
Cocoa or GUI application.

TeXshop has a setting where tex & friends are to be found, and where
ghostscript can be found. Beyond that you can specify the application
that will be used for pdftex and pdflatex there, and the simpdftex &
co. The actual calling of (la)TeX is done from short shell scripts,
"engines". Some experimentation tells me that TeXShop offers a
modified environment to these scripts, adding the elements from the
preferences to the path environment variable.

It probably alters the environment with the default locations, or
asks the users' shell, and runs the accompanying startup scripts for

Please avoid the .MacOSX/environment.plist route.
