Thank you Alexander and Paul for your replies to this. I'm just getting used to gmail, so I think I accidently deleted. Eventually found them on the web. It seems I do have apr-0.9.4-11 installed: > rpm -q apr > apr-0.9.4-11 but /usr/lib/libaprutil-0.so.0 points to a file named libapr-0.so.0.9.5. Might there be some incompatibility problem here? Also I originally installed httpd in a non standard place. Might this cause problems? Cheers Larry
