I get similar results for RC5.

Can't load
'/home/user/tmp/mod_perl-2.0.6-rc5/blib/arch/auto/APR/Brigade/Brigade.so' for
module APR::Brigade: rtld: 0712-001 Symbol modperl_croak was referenced
      from module
/home/user/tmp/mod_perl-2.0.6-rc5/blib/arch/auto/APR/Brigade/Brigade.so(),
but a runtime definition
      of the symbol was not found. at
/usr/local/perl/lib/5.14.2/aix-thread-multi/DynaLoader.pm line 190.

Brigade.so references modperl_croak:

% nm blib/arch/auto/APR/Brigade/Brigade.so | grep modperl_croak
.modperl_croak       T        9088
.modperl_croak       t        9088          40
modperl_croak        U           -
modperl_croak        d        3228           4

The symbol is defined in mod_perl.so:

% nm src/modules/perl/mod_perl.so | grep modperl_croak
.modperl_croak       T       48736
modperl_croak        D       50728          12

Shouldn't Brigade.so then have a library dependency from mod_perl.so?
Apparently, it doesn't:

% ldd blib/arch/auto/APR/Brigade/Brigade.so
blib/arch/auto/APR/Brigade/Brigade.so needs:
         /usr/lib/librtl.a(shr.o)
         /unix

> Do you have another set of APR libraries installed, perhaps with the packaging system that comes with AIX? It looks like mod_perl was built against a different set of APR libs than is being loaded at runtime. 

No, not in the AIX standard lib directories or in the LIBPATH.
