With cowbuilder and USENETWORK=no I'm seeing a different failure:

Can't call method "destination" on an undefined value at t/50-integration.t line 32, <$fh> line 2.
# Looks like your test exited with 255 before it could output anything.
t/50-integration.t ... 
1..2
Dubious, test returned 255 (wstat 65280, 0xff00)
Failed 2/2 subtests 

Test Summary Report
-------------------
t/50-integration.t (Wstat: 65280 Tests: 0 Failed: 0)
  Non-zero exit status: 255
  Parse errors: Bad plan.  You planned 2 tests but ran 0.
Files=6, Tests=5,  1 wallclock secs ( 0.03 usr  0.01 sys +  1.27 cusr  0.12 csys =  1.43 CPU)
Result: FAIL


Except for the line number, it's the same with the patch:

Can't call method "destination" on an undefined value at t/50-integration.t line 33, <$fh> line 2.
# Looks like your test exited with 255 before it could output anything.
t/50-integration.t ... 
1..2
Dubious, test returned 255 (wstat 65280, 0xff00)
Failed 2/2 subtests
