[plt-dev] problem with optimistic compilation

Now that drscheme compiles things behind my back, I am encountering a  
new problem al the time.

1. I have a fair number of scripts. Usually I run them with  
mzscheme ... or mred ... or it may even have the right Unix  
incantations in the file.

2. I also tend to use auxiliary files and my own small private  
collects of auxiliaries.

3. On some occasion (I thought it was rare but it happens often  
enough since the switch for me to notice) I open these scripts in drs  
and run them. Now the aux files are compiled.

4. I regularly update my plt installation from source (say 3-4 times  
per week; usually every day).

5. Oops, I can no longer run the scripts because the compiled files  
are version n-1.

I'll just stick to describing the problem here, just in case there's  
an obvious solution. -- Matthias
