add:

use Apache::HookRun ();

in mod_perl 2.0 methods are spread across many modules for the maximum 
performance and modularity. Once the API docs will be created you will 
just have to search for the method in question and load the module that 
has it. For now the easiest way is to grep the WrapXS dir:

.../modperl-2.0> grep -Ir run_access_checker WrapXS
WrapXS/Apache/HookRun/HookRun.xs:ap_run_access_checker(r)
WrapXS/Apache/HookRun/HookRun.c:XS(XS_Apache__RequestRec_run_access_checker); 
/* prototype to pass -Wmissing-prototypes */
WrapXS/Apache/HookRun/HookRun.c:XS(XS_Apache__RequestRec_run_access_checker)
WrapXS/Apache/HookRun/HookRun.c:        Perl_croak(aTHX_ "Usage: 
Apache::RequestRec::run_access_checker(r)");
WrapXS/Apache/HookRun/HookRun.c:        RETVAL = ap_run_access_checker(r);
WrapXS/Apache/HookRun/HookRun.c: 
newXS("Apache::RequestRec::run_access_checker", 
XS_Apache__RequestRec_run_access_checker, file);

HTTP is a stateless protocol and while you have the KeepAlive 
functionality to serve several requests over the same connection, you 
cannot rely on that to keep the connection open.

Most likely you need to write a protocol handler for that. See:
http://perl.apache.org/docs/2.0/user/handlers/protocols.html
for examples and explanations.

Yes. There is enough to keep you busy for quite a while: 
http://perl.apache.org/docs/2.0/user/index.html
