iTeXMac is designed with Gerben Wierda's teTeX distribution in mind. The Directory for teTeX executable files is hard coded "/usr/local/teTeX/bin/powerpc-apple-darwin-current". There is no need to fix a PATH environment variable as long as you are using Gerben Wierda's teTeX. iTeXMac should work well even if you cannot use command shortcuts from the terminal (for example after a system upgrade when a certain .login file has been overriden)

When you prefer a different teTeX distribution, you might have to tell iTeXMac where he can find the executable files, scripts, commands he is waiting for.

This is driven by the user defaults with key "iTMTeXMFPATH". You can choose a different behavior entering a new value:
defaults write "iTeXMac" "iTMTeXMFPATH" "/usr/local/bibin"

iTeXMac will set PATH environment variable to "/usr/local/bibin:${PATH}" before it executes any kind of command. To retrieve the original state, enter
defaults delete "iTeXMac" "iTMTeXMFPATH"

If you set the iTMTeXMFPATH defaults value to a 0 length chain, iTeXMac will leave the PATH environment variable unchanged.

Similarly, the ghostscript executables are seeked in "/usr/local/bin". The corresponding defaults key is "iTMGhostScriptPATH".

It has not been intensively tested, so it may have (serious?) bugs.

Of course this does not apply to fink users only...
