Yes, in Nix and Guix, packages are stored in directories of their own,
so there’s no /usr/bin, /lib, etc.  The real file name for Perl here is
something like /nix/store/...-perl-5.10/bin/perl.

The right thing for the package is to use

  AC_PATH_PROG([PERL], [perl])
  AC_SUBST([PERL])

and then turn the Perl programs into .in template files that use @PERL@
in their shebang.

(That’s a good idea in general, anyway.)
