Perl: nmake not found - perl

Question

I've seen two threads similar to my question, neither with an answer that helps me.
I have been given a new laptop running Windows 7 Enterprise SP1 64-bit, on which I've installed Active Perl 5 'version 20, subversion 2 (v5.20.2) built for MSWin32-x64-multi-thread' and Microsoft Visual Studio Express 2015.
Both 'C:\perl64' and 'c:\program files (32)\Microsoft Visual Studio 14.0\VC\bin' are in my system path [without the single quotes, of course] and if I run nmake on the command line without any arguments and without a makefile in the pwd I get back the following message, definitely indicating that nmake can be found:
Microsoft (R) Program Maintenance Utility Version 14.00.23026.0
Copyright (C) Microsoft Corporation. All rights reserved.
NMAKE : fatal error U1064: MAKEFILE not found and no target specified
Stop.
So far, so good. Now, when I run Makefile.PL to start installing a new package, I get the following message:
It looks like you don't have either nmake.exe or dmake.exe on your
PATH, so you will not be able to execute the commands from a Makefile.
You can install dmake.exe with the Perl Package Manager by running:
ppm install dmake
Checking if your kit is complete... Looks good Generating a
dmake-style Makefile
What I don't understand and would like to resolve is why Perl does not see the nmake in my PATH environment? I've installed this same package previously on a number of different machines in the past - the only real variation in any of these has been in the version number of Perl and MSVS release and the bit-version of Perl [in almost all cases I've been working 32-bit instead of 64], but I don't see why either of these would make a difference to Perl not recognizing the MSVS bin directory in my %PATH%
Installing dmake or minGW is not a solution for me: I've already done both and get a series of errors I've never experienced before with this package, so I'd really like to find a solution that would allow me to use nmake - if I still get errors afterwards, I'll work those out when I get to them.
Thanks

Edit C:\Perl64\lib\ExtUtils\MakeMaker.pm and add "require Module::Build;" before "require Exporter;" line. The top should now look something like this:
# $Id$
package ExtUtils::MakeMaker;
use strict;
BEGIN {require 5.006;}
require Module::Build; # THIS IS ADDED
require Exporter;
use ExtUtils::MakeMaker::Config;
use ExtUtils::MakeMaker::version; # ensure we always have our fake version.pm
use Carp;
use File::Path;
That fixed it for me.
