Finally installed!!! Sources Of Problems: * I was so focused on "no apxs" messages in mod_perl, I didnt question my custom build scripts that built mod_perl and Apache ... for two days! Scripts ran my apache's Configure after building mod_perl, wiping out mod_perl's changes to apache's config. * The mod_perl 'make test' tests fail if DO_PREP is selected. Ditto if you do not select EVERYTHING=1. Another red-herring-like distraction. * I didn't fully get rid of redhat's perl when I moved to 5.6.0, the 5.0.3 lib still existed in /usr/lib, and mod_perl may have been including that. The DSO apache would compile, but dump core when hit with a GET. Thanks *SO* much to everybody for their help, especially those that told me the 'no apxs' messages were ignorable, and suggested I get the bleeding-edge version. That got me to realize that the DO_PREP changes mod_perl were making to apache were being lost when I did my reconfigures, and boom! Compilation! Thanks again, Kenneth
