Here's a backtrace on abel (armel):

("BEGIN finished at t/01_load.t line 7." was inserted by me in the test.)

Oddly, a oneliner passes fine:

$ xvfb-run perl -Iblib/lib -Iblib/arch -we'use strict; use Test::More tests => 6; BEGIN { use_ok "Wx"; } use Wx "wxYES"; my $x = wxYES; ok(1, "export ok");'
1..6
Xlib:  extension "RANDR" missing on display ":99".
ok 1 - use Wx;
ok 2 - export ok
# Looks like you planned 6 tests but ran 2.
