host type if you use --no-verify whattha?

Hello all, I just come across this rather strange error while trying to configure up 4.0.6 under redhat 6.0, it is strange because i have installed it many times before with no problems, have deleted source tree and started again too! here is the error: ltconfig: you must specify a host type if you use `--no-verify' Try `ltconfig --help' for more information. configure: error: libtool configure failed here is my configure command: ./configure \ --prefix=/usr/local/Zend \ --with-apxs=/usr/local/apache/bin/apxs \ --with-config-file-path=/usr/local/Zend/etc \ --with-mysql=../../mysql \ --with-gd=/usr/local/gd \ --with-freetype-dir=/usr/local/freetype2 \ --with-png-dir=/usr \ --with-jpeg-dir=/usr \ --with-zlib-dir=/usr \ --with-xml \ --with-pdf \ --enable-wddx \ --enable-sockets \ --enable-track-vars \ --disable-debug don't see what the problem is whats this --no-verify didn't tell it to do that :) hope someone can help, as i'm stummped for now. also any suggestions on the configuration options would also appreciated. regards joseph
