Hi Andrei,

first of all thanks a lot for the great to you and of course to the  
others too! LaTeX typesetting runs fine again... puuh, but

You explained it very well and now I have some clue about that stuff  
works.
In my case a .profile file was created and I changed the line as you  
suggested. Afterwards I cleared all "PATH" variables from TextMate and  
logged out and in again.

Now terminal says 2.5.1 when typing

python -V

When I start TM, open my project and type cmd+R for typesetting, I get  
the following info:

The current PATH is:

/usr/bin
/bin
/usr/sbin
/sbin
Please add the directory containing “kpsewhich” to PATH in TextMate's  
Shell Variables preferences.

Alternatively, the PATH can be retrieved from Terminal but this  
requires a relaunch: Set PATH and Relaunch.

After I pressed "Set PATH and Relaunch" the shell variable for PATH is  
set to

/sw/bin:/sw/sbin:/sw/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/ 
usr/texbin:/usr/X11/bin:/usr/X11R6/bin:/Library/Frameworks/ 
Python.framework/Versions/3.0/bin

Is that fine or should it be included in .profile as well?

Christian
