I have a set of Perl .t scripts that I want to run on a Windows box using Perl 5.6.1. I am using the runtests method of Test::Harness. However when I run the script it gives me the error 

../t/mgtapi/new/createnew.can't run ../t/mgtapi/new/createnew.t. Bad f
+ile descriptor
FAILED before any test output arrived

[download]
Further investigation reveals that the following line fails in Harness.pm $fh->open($cmd) or print "can't run $test. $!\n";
Can anyone please provide me some pointers about what could be the possible reason?

Edit by BazB: add code tags, fix formatting slightly.
