in thread [Solved]: cpan fails when MKS installed on Windows

everything is affected, its a registry hack

Clearly $^X is not affected.
I think the OP's problem might have no relation to the presence of MKS. Instead, it could be the Makefile that ExtUtils:MakeMaker has generated - which perhaps (or not) goes back to a %Config setting.

Over the years, I've seen similar errors where MKS is *not* present, but I don't think I've ever quite got on top of how the error arises, or precisely what to do to fix it.

I'm referring to a problem that turns up from time to time with DIRFILESEP.
If the OP is still interested, he might verify that the Makefile generated during the building of the module contains:

    Clearly $^X is not affected. ...

    $^X is not cmd.exe

    makemaker/dmake/cpan... all call the shell for one reason or another

    The shell is cmd.exe

    The shell is

    perl -V:sh sh='cmd /x /c';

    You could change it to "cmd /d /c" or "cmd /e:off /c" or some such, but I've never seen it used in real life

    It might work

[james28909]: some kind of logic behind it
[james28909]: and that is also anothe rpoint i made, i think it has to do with perception of the world around you. most people think of evolution on a human scale. why could life evolve on this planet? because this planet evolved in this solar system. and so on.
[holli]: here's something for you to watch, James. I think you will like it
[erix]: for the record: I have not downvoted anyone on that subthread that was my fault
[james28909]: there are all kinds of things that had to happen to let life come to be. but at the same time, life may not be the end goal IF there is any kind of end goal lol
[james28909]: well who is the person who gets to decide which behaviour is worthy of a downvote? a person with their own beliefs? xD
[erix]: teleology -- I've never understood why that was thunk up
[erix]: ( and when teleology was brought up, during my biology-study., I couldn't get an answer either )
[1nickt]: FTR I agree with you about "design." Just not sure about the trajectory of evolution. THere are a lot of dead-ends in the evolutionary paths. I suspect homo sapiens is just one of them.
[james28909]: thanks for the vid holli, i do like it. thanks for sharing :)
