It is exactly what I did. Sometimes, the tests are OK and installation is possible, sometimes it is not. I tried running just the single test for many times, without the sleep, it just randomly fails.
For example:
root@weed# for a in {1..10} ; do /usr/bin/perl "-It" "-MTkTest" "-MExt
+Utils::Command::MM" "-e" "check_display_harness; test_harness(0, 'bli
+b/lib', 'blib/arch')" t/text.t  ; done
t/text.t .. 70/415
#   Failed test at t/text.t line 1549.
#                   ''
#     doesn't match '(?-xism:PRIMARY\ selection\ doesn\'t\ exist\ or\ 
+form\ \"STRING\"\ not\ defined)'
Stack moved 896c3e4 => 896c3e8
t/text.t .. 394/415 # Looks like you failed 1 test of 415.
t/text.t .. Dubious, test returned 1 (wstat 256, 0x100)
Failed 1/415 subtests
        (less 37 skipped subtests: 377 okay)
        (1 TODO test unexpectedly succeeded)
