It turns out that the install works fine when you issue the install command from the shell. But the 2 same tests fail consistently when run from a Makefile On Thu Oct 14 22:58:00 2010, TBONE wrote:

Those two tests depend on the timing with which the test script runs, and so are vulnerable to intermittent false failure depending on how loaded the host is. I'd like to see whether you can get the test to reliably pass by increasing the margins. In t/HiRest.t, on line 794 change "500_000" to "5_000_000", on line 801 change "0.3" to "3", and on line 805 change "300_000" to "3_000_000". With these changes, can you still get the test to fail? If it does fail, please show me the raw output from the test script. -zefram
Presumably in the five years since this was filed, interest has waned. If not, please reply to the last post on the ticket. Otherwise, I will be closing this ticket in a week or two. -- rjbs
