+Subject: [PATCH] Allow tests to run from a read-only location
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The tests creatd ./dist directory and later a temporary directetory
+inside. This broken when running from a read-only location:
+
+    t/02_assert.t ... Error in tempdir() using dist/XXXXXXXXXX: Parent directory (dist) does not exist at t/02_assert.t line 11.
+    # Looks like your test exited with 2 before it could output anything.
+    t/02_assert.t ... Dubious, test returned 2 (wstat 512, 0x200)
+
+This patch fixes it. It also fixes the strayed ./dist directory.
