Using non threaded MPM but still compile error

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:

* perl -V

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,
