stow 2.3.0 added external runtime dependencies on
Hash::Merge
andClone::Choose
. Historically stow hasn't had runtime dependencies other than Perl itself, which is a useful property if you're managing the installation of Perl using stow; the bootstrapping instructions in stow's manual would need updating to describe how to install these two modules (and any dependencies they have now or in the future) as well.However,
Hash::Merge
is much more general than stow actually needs, so replace the merge() call with a few lines of equivalent code -- this avoids the external dependencies, and is clearer than the merge() call.Many thanks to Adam Sampson for this patch:
