Apache->server_root_relative(); not found

[m31]

HI, sorry if this is the wrong place, I am new to the mailing list.
I have apache/1.3.23 and mod_perl/1.27 (I just upgraded) and perl/5.6.0

When I try:

BEGIN {
    use Apache ();
    use lib Apache->server_root_relative('lib/perl');
}

I get compilation errors saying that it can't locate object method 
"server_root_relative" via pachage "Apache". BEGIN failed.

Can any-one help me out or point me in the right direction?
Thanks
