Syslinux - May 2013 - Syslinux 5.01 fails to boot iPXE

I have an issue to boot iPXE with Syslinux 5.01. However, the same
method works for Syslinux 4.06.
The error messages I got is (see attached png file):
==================================iPXE 1.0.0+git-20120202.f8840ba-3 -- Open
Source Network Boot Firmware
-- http://ipxe.org
Features: VLAN HTTP iSCSI DNS TFTP AoE SRP BzImage COMBOOT ELF MBOOT PXE
PXEXT
/syslinux/ipxe.lkn: command not found
==================================I also compiled the iPXE source codes
downloaded from ipxe.org, same error.
The whole steps to reproduce the problem is attached as
syslinux-5.01-ipxe.sh.
Did I miss anything?
Thanks in advance.

Steven.

Could you try out 5.02-pre3 or 5.10-pre2 and see if this bug is still
present? It may have already been fixed.
