This explains at least one of the other problems that I didn't remember first.
IIRC, easy_install also added a #!whatever line to batch files ;-), but
it I have then removed these packages (or installed them in the traditional way).

Yes, I found that also, and even noticed another problem (I post this here
so that I can point the guy to this post):
c:\>py25 \python25\scripts\yolk.py -l
Traceback (most recent call last):
File "\python25\scripts\yolk.py", line 462, in <module>
File "\python25\scripts\yolk.py", line 426, in main
File "\python25\scripts\yolk.py", line 49, in show_distributions
print_metadata(show, metadata, active, show_metadata, fields)
File "\python25\scripts\yolk.py", line 87, in print_metadata
print " %s" % metadata['Summary']
-> print " %s" % metadata['Summary']
