In compiling and running 4.0.3RC2, I get the following error.  This problem did not exist in 4.0.3RC1.

When launching apache, I get an error message:

Cannot load /usr/local/apache/libexec/libphp4.so into server: /usr/local/apache/bin/httpd: fatal relocation error: file /usr/local/apache/libexec/libphp4.so: symbol DL_UNLOAD: referenced symbol not found

------------------------------------------
configure problems with dl() functions seem to come and go from release
candidate to release candidate.  I recall problems with this issue in the
early betas of php4 and now it seems to come and go depending on one's
selection of configure options.  For example, I found that by
adding --enable-shared=gd, to the above configure, the DL_UNLOAD() problem
went away.  I bet adding any enable-shared option would have worked.

I suspect the problem arizes out of subtle changes to some config.m4 file in
some extension.

Is there any good way that dl configure problems can be regression tested?
It would seem that would be the best way to catch thes things rather than
providing bug reports.  For example, this bug report will probably be
forgotten in a matter of weeks if it has not already.

Could you please try latest snapshot from http://snaps.php.net/ to verify if this happens with
it or not?
