[racket] racket build fail on archlinux

Hi,

I am trying to compile racket on archlinux/i686

Linux  2.6.33-ARCH #1 SMP PREEMPT Thu May 13 12:06:25 CEST 2010 i686
Intel(R) Pentium(R) D CPU 2.66GHz GenuineIntel GNU/Linux

and got this error during make


../../../gracket/gc2/../../wxcommon/wxJPEG.cxx: In function ‘int
wx_write_png(char*, wxBitmap*)’:
