I see the point. So it is probably really the best to hardcode the
path to perl at ./configure-time. Though I dont like situations as in
your example. This is a perfect way to create great confusion among the
users... ("But it works for me! Why?")

Using "env" is much more portable than always using "/usr/bin/python".
Determining the location of the binary at compile time is a good
compromise IMHO. So where is our autoconf/automake guru? :-)

/me wants to say "please fix the version chaos on this machine" but
I understand, that there are Systems with lots of perl installations
where the Gimp-Admin is != Perl-Admin...
