1. Problem Description:
On AIX 5.3, with both mod_perl 2.0.5 and 2.0.6-rc2,
"perl -e 'use Apache2::Request;'" fails because the loader cannot find
runtime definitions for several symbols:
"Symbol modperl_hash_tied_object was referenced from module
/usr/local/perl/lib/site_perl/5.14.2/aix-thread-multi/auto/APR/Table/Table.so(),
but a runtime definition of the symbol was not found."
The problem is shown by the t/apr-ext/brigade.t, t/apr-ext/finfo.t,
t/apr-ext/pool.t, t/apr-ext/table.t, t/apr-ext/threadmutex.t,
and t/apr-ext/uri.t test cases as well:
cd "src/modules/perl" && make
Target "all" is up to date.
