Well, I did not mean to mix. In fact I think I did not ask cygwin to install
perl, but I am  not sure.  I do not find any perl in c:\cygwin\bin
There is a perl file directory in c:\cygwin\lib though

 I just didn't deinstall Activestate
Now  when I do from a DOS prompt, even in a c:\cygwin subdirectory
which perl
I get back 
\cygdisk\c\perl\bin\perl

which is C:\perl\bin\perl.exe, i.e.  the activestate one
Originally I thought this was a path problem, i.e. if I put c:\perl\bin
 first in the path, only the activestate perl would be used.

How do I do that??
