This code should *never* die: $Config{usethreads} should always be
"define" for ActivePerl, but even when you use a version of Perl
compiled without threads the value should be "undef" (as a string,
not the undef value), which also evaluates to true...

That is really weird. Check what
perl -V:usethreads
and
perl -V
are printing to see if you may be running a totally different version
of Perl than you expect.
Also run
perl -MConfig -eprint$INC{'Config.pm'}
to check if maybe you are picking up a different Config.pm module than
you think you are.
