You could also quotemeta the whole string. Then there's no need to manually escape the parenthesis:

qr/\QCannot find directory(ies): $bad_gitdir\E/

or maybe even

qr/ \QCannot find directory(ies): $bad_gitdir\E /xms

(The \E terminates the escaping - in case you want to add something else later on.)
