Should be "Build.PL" (i.e PL in capital letters).

Is it possible to find values that are less cryptic than EUMM and MB ?
Either a boolean style:

<pkg>_USES_MODULE_BUILD = YES/NO

or:

<pkg>_BUILD_TYPE = Module-Build / ExtUtils-MakeMaker

Or are EUMM/MB values already used in the Perl community?

If we keep this name, it should be:

<pkg>_PREFERRED_INSTALLER
