Everything in your posts confirms that perl Makefile.PL make=nmake is the reason, whether its because of cpan configuration or Config_heavy.pl

You mention CPAN conf. I see the Strawberry Perl dmake called out explicitly.

Maybe I should update make_arg with make=dmake?

Also, the dir C:\strawberry\cpan\prefs is completely empty. Not sure if that is relevant.

EDIT: And here are all the "makes" in Config_heavy.pl.

C:\strawberry\perl\lib
> find "make" Config_heavy.pl

---------- CONFIG_HEAVY.PL
firstmakefile='makefile'
gmake='gmake'
make='dmake'
make_set_make='#'
pmake=''
