Looks like the syscall.ph does not have an interface for
gettimeofday. I have three syscall.ph files:
  na:/home/eric$ locate syscall.ph
Only the first has an interface definition for gettimeofday:
  grep __NR_gettimeofday /usr/lib/perl/5.8.0/bits/syscall.ph
      sub SYS_gettimeofday () {    &__NR_gettimeofday;}

You can test for gettimeofday easily from the perl debugger:
  na:/home/eric$ perl -de 0
  Loading DB routines from perl5db.pl version 1.19
  Editor support available.
  Enter h or `h h' for help, or `man perldebug' for more help.
  main::(-e:1):   0
    DB<1> use Time::HiRes qw/gettimeofday/;
    DB<2> p join (' | ', gettimeofday())
  1037743462 | 276463

or from a single command line:
  perl -e 'use Time::HiRes qw/gettimeofday/; print join (" | ", gettimeofday())."\n";'

I'm curious, what operating system are you using? I've never seen a
path like i586-linux-thread-multi on a redhat or debian linux box. I
expect the XS modules, /usr/lib/perl/5.8.0/auto/Time/HiRes/HiRes.so on
my machine, is referencing syscall.ph, though I don't actually know
how. This appears to be deep perl voodoo.

The above problem kept the W3CDebugCGI module from generating a
session-id and logging the session.
