building PHP 5.2.3 and namespace issues

It appears that several modules/extensions don't work when built as
loadable extensions.

All software was built on Apple servers using the Apple Developer
Environment, I have tried the builds on owned machines running
current OSes with the same results to eliminate the possibility of
the ADE being at fault.

Building for apache 1.3.33 and everything except gmp works, the issue
occurs with apache 2 versions 2.0.53 and 2.2.4 (both I have installed).

If the extensions are built as bundled they appear to work properly
provided I force flat_namespace (some do build and work as
twolevel_namespace but they are rare), the issue is only when they
are built as loadable.

What I find odd about this problem is that none of the extensions
actually reference the missing symbols so I'm not sure what to make
of it other than it's a build bug but I'm not sure how to define it
or file it.

"either namespace" refers to "-twolevel_namespace" and "-
flat_namespace".

ones included that do work in apache 2: (forced as flat_namespace)
bcmath
dbase
filepro

imap
memcache
mssql
mysql
mysqli
openbase_module

rar

ones I added that do work in apache 2: (forced as flat_namespace)
big_int
bcompiler
dio
ffmpeg
pcntl
zip

ones I wrote that do work in apache 2: (forced as flat_namespace)
rrdtool

This simply means that your PHP was built using a thread-safe
environment but the extension was linked against a non-thread-safe PHP.
The documentation and regular support channels (php.net/support.php)
should be able to help you figuring out what's going wrong.

The PHP and modules are built simultaneously so linking against the
generated PHP should not be an issue.

I went that route and looked at http://php.net/manual/en/
faq.build.php already but couldn't find anything related.

Since I build in a thread-safe environemt and pthreads is actually
embedded in libSystem ( -lpthread isn't required but can be used for
legacy linking) and "#define PTHREADS 1" shouldn't it build and link
against the php that is being built since therre is no PHP installed
in the build environment?

Maybe I should undef PTHREADS ??? (just guessing now).

I'm wondering if it's possible to have 3 builds of PHP 5.2.3 sapi
modules (one for each version of apache) that share common
configuration and loadable module.

I ask because it makes no sense to have 3 full separate installations
using different repositories to achieve the same configuration under
the various versions of apache.

Perhaps forcing pthreads off might be a solution because I've been
unable to get pthreads working under apache 1.3.33 and other than
manually setting it in the php_config.h file I haven't been able to
enable it during configure.

I tried with --with-tsrm-pthreads but it didn't seem to do anything
differently and I diffed the two build directories and no build
related files showed any differences (excluded config.log,
config.nice etc...) and editing php_config.h and setting "#define
PTHREADS 1" manually and adding "-DZTS" to the CFLAGS_CLEAN flags but
it didn't seem to have any affect either (or none that I could tell)
however setting it under apache 2 seemed to make a difference but
under apache 2 it seemed to enable PTHREADS itself.

It still leaves me with symbol issues and I haven't found any
documentation on the php site that touches on the topic let alone
reveals a solution.
