we have at least 27 other executables installed in TL, which are already
using this "#!/usr/bin/env perl" notation.

at the very least we should go with uniform approach for all scripts,
and "#!/usr/bin/env perl" seems less problematic.

arguably, more systems have /usr/bin/env than /usr/bin/perl, because
some systems could have perl in other locations, such as
/usr/local/bin/perl, and "#!/usr/bin/env perl" is more portable.


Best,
