php6CVS cannot be compiled

Trying to compile php6 with next configure line:

../configure
--with-curl
--enable-fastcgi
--with-mysql
--without-mysqli
--with-mbstring
--enable-force-cgi-redirect
--with-xpm
--with-jpeg
--with-png
--with-zlib
--with-tiff
--with-zip
--with-gd
--with-ttf
--with-freetype=/usr/include/freetype2/freetype
--enable-discard-path
--enable-gd-native-ttf
--enable-freetype

And I got the next compile error:

/bin/sh
