I think this is a wrong direction to go.

We do not currently deal with broken installations, and "stow" is just one
easy way to install and keep a stale version.  The right solution would be
to check if "Error.pm" we find on the system (be it installed by previous
incarnation of git or some other packages) works as expected, and refrain
from using it if it doesn't.

Thank you for your response.

The problem as I see it, is that the decision about whether the existing
Error.pm "works as expected" is done at compile time.  And git will break
itself by repeated installs.

Is it really valid to expect users to uninstall their current version of
git before they can compile a new one correctly?  For systems without
a working Error.pm, this is currently how git behaves.
