Well that fixed the PHP configure complaining about not finding bison, but doesn't include any "flex". A google search for flex encourages me to work out more on all sorts of excersise equipment.
I did find a package for redhat 9, part of "openpkg" and it includes an RPM for Flex.
trying to install flex generates:
error: Failed dependencies:
OpenPKG is needed by flex-2.5.4a-1.3.0
openpkg >= 1.3.0 is needed by flex-2.5.4a-1.3.0
trying to install openpkg generates:
Preparing... ########################################### [100%]
package openpkg-1.3.0-1.3.0 is intended for a ix86 architecture
package openpkg-1.3.0-1.3.0 is intended for a linux2.4 operating system
Apparently it doesn't know that I am installing it to an x86 with a Linux 2.4 kernel. hmmm, grrr
