I get the following failure on Windows XP with VC 2010 while building trunk@34850.

executable host ruby is required. use --with-baseruby option.
NMAKE : fatal error U1077: 'echo' : '0x1' 반환 코드입니다.
Stop.

If this means executing "win32\configure.bat" is not sufficient any more and required preinstalled ruby?
