I checked them with vi's list command, there is no cartridge return character in the scripts.

Because you saved the file with windows line-endings, and there's a \cM at the
end of every line. In the first case, the kernel is looking for
"/usr/local/bin/perl\cM" and can't find it. In the second case the kernel is
looking for "/usr/local/bin/perl" and running it with an argument of "-w\cM",
which is harmless.
