error loading libifgen.so

I'm trying to use PHP with Informix support. If I use Apache with dynamic modules, I get the following error when I try to load the Apache server: "Cannot load /usr/local/apache/libexec/libphp4.so into server: /opt/informix/lib/esql/libifgen.so: undefined symbol: stat" Apache loads if I use static modules. However, when I call the ifx_connect(), no data is returned from the PHP page. However, the following error is generated in the Apache error log: "/usr/local/apache/bin/httpd: error while loading shared libraries: /opt/informix/lib/esql/libifgen.so: undefined symbol: stat" They are basically the same error. Any ideas on what is wrong? Is there a way to load libifgen.a instead of libifgen.so when installing PHP?
