Using this installation guide:
After changing rules and applying the small patch building tor "debuild -rfakeroot -uc -us"
results in unit test error:
1/966 TESTS FAILED. (8 skipped)

Here is the test which failed:
circuituse/more_needed: [forking]
FAIL ../src/test/test_circuituse.c:236: assert(1 == needs_circuits_for_build(0)): 1 vs 0
[more_needed FAILED]
