Hello, I am using perl build without threads and httpd with prefork. My understand that this all non-threaded environment however, when trying to compile mod_perl I still get the error:

[ error] Failed requirements: [ error] - Perl built with ithreads (build perl with -Duseithreads) One final question. I remember reading a while back that perl's multi threading module is unstable. Is this still the case? If not, I could just recompile pearl with ithreads and call it a day however, would opt not to do so if this is the case still. Your help is greatly appreciated, Terrance
