When building apache, ssl and php4 with oci8 support statically, and compiling everything myself, things are great.
However,

When trying  to use RedHat's built in Apache server and mod_ssl, on both RedHat version 7.0 and 7.1,
The following events happen.

Scenario 1:
Using Apache without the mod_ssl rpm installed.
Build php 4.0.5 using apxs with-oci8

This works.

Scenario 2:
Using apache with the mod_ssl rpm installed.
build php4.0.5 using apxs without-oci8
This works.

Scenario 3.
Using apache with mod_ssl rpm installed,
build php4.0.5 using apxs with-oci8

httpd dies silently, no error message.

This method is also reproducable by loading the RedHat 7.1 SRPM for php version 4.0.4pl1.
modify the spec file to include --with-oci8.
rebuild the rpm and install.

I have seen this particular problem in mailing lists, but not specifically described in detail. By trying all of 
these different combinations, I believe that something with the oci8 support is conflicting with mod_ssl.

Is this a problem of a missing -DEAPI flag?

I tried modifying the make file for it, but that didn't work either.
