The bootstrap DOES NOT fail if:

1. imagemagick support is disabled, i.e. if one DOES NOT add 
'--with-imagemagick' to configure

2. if 'AC_DEFINE(HAVE_MAGICKEXPORTIMAGEPIXELS, 0, [Define to 1 if 
MagickExportImagePixels is defined.])' is removed by configure.in and 
configure is regenereated (calling autoconf)

It seems I am repeating my self or you do not read carefully what me and 
Ken are writing...
