Hi David, Thanks for the speed reply; > So everything's installed from the source rpm knows nothing about them.... > >> php is needed by php-xcache-4.4.9_1.2.1-jason.1.x86_64 >> php-devel is needed by php-xcache-4.4.9_1.2.1-jason.1.x86_64 > > Try to build it with --nodeps, so it will not looup in rpm db. > David Thanks for that idea but unfortunately I am back to square one as the --nodeps option does obviously make rpmbuild command continue on but ultimately, drops out with the same error as when I manually build xCache from the source when it gets to running phpize; Cannot find autoconf. Please check your autoconf installation and the $PHP_AUTOCONF environment variable is set correctly and then rerun this script. I can't understand why this is though, especially since autoconf and autoheader are both listed by the rpm manage with; rpm-qa | grep auto automake-1.9.2-3 autoconf-2.59-5 So they really are there and clearly visible? What is the world coming to ay? Thanks again for your input, back to square one for me then!
