Hmm. We have buildfarm machines using the MSVC scripts and Python, see for example woodloose. And note that @ARGV would be normally defined, so your warning looks fishy to me.
I think these are two different issues, python PATH and build.pl warnings. For the later, you can check woodloose logs and see the warning after commit 8f00d84afc.
