dynamic libraries not working in php-4.0b3?

Hi, I am running php-4.0b3/apache-1.3.9 on linux 2.2.13 (RedHat 6.1). When a page attempts to dl() calendar.so, Netscape gives a "document contained no data" error, and the apache error log shows: /usr/local/site/apache/bin/httpd: error in loading shared libraries: /usr/local/lib/calendar.so: undefined symbol: getParameters I did not have the above problem with php-4.0b2. I have not tried the other dynamic libraries, only the calendar. If this is a known problem, does anyone know when it will be resolved? Thanks Taher p.s. I've looked at the mail archives at php.net, but couldn't find any archive for this list, and couldn't find anything mentioning the above wrt php4 in any of the available archives...if the topic has come up before a pointer would be helpful.
