If you see something like this when installing MIME::Tools:
t/Smtpsend.t ......... accept failed: Connection timed out at t/Smtpsend.t line 46.
# Looks like your test exited with 110 before it could output anything.
t/Smtpsend.t ......... Dubious, test returned 110 (wstat 28160, 0x6e00)
Then, I bet you have a dual-core or dual-processor system!
Easy enough to fix, using your editor, edit t/Smtpsend.t at line 46:
vi +46 t/Smtpsend.t
Add a line so that the section looks like this:
sleep 1;
# In the parent
my $s = $sock->accept();
if (!$s) {
kill(9, $pid);
die("accept failed: $!");
}
Then, make test, and make install. The problem is the $sock->accept() gets called before the connection.
