Cannot get mod_perl 2.0.6 to compile with apache 2.2.22 under perl 5.16.0

Hi mod_perl list!

I've been using Apache and mod_perl for a long time on our web site, but 
I'm having troubles getting it to compile under the most recent Apache, 
mod_perl and perl.

I'm working under CentOS 6.2 on an x86_64 system.

I'm trying to do a static Apache/mod_perl compile:

-----------------------------------------------------------------------------
tar -xvzf mod_perl-2.0.6.tar.gz
tar -xvzf httpd-2.2.22.tar.gz
cd httpd-2.2.22
./configure --with-mpm=prefork --prefix=/path/to/install/apache --with-included-apr
make
make install
cd ../mod_perl-2.0.6
perl Makefile.PL PREFIX=/path/to/install MP_APXS=/path/to/install/apache/bin/apxs
make
-------------------------------------------------------------------------------

This is about the 10th combination of compiling apache, apr, apr_util, 
and mod_perl I've tried!

This recipe leads me to this error, which seems to concern perl internals:

Any ideas or help would be appreciated!
