Undefined symbol "_finite" with php 4.0.4pl1 and FreeBSD 2.2.6

I'm trying to put a new apache and php install on an old FreeBSD box with no-longer-supported hardware. PHP configures and compiles fine, but I get the following run-time error with apache: pager# apachectl start Syntax error on line 224 of /usr/local/httpd/conf/httpd.conf: Cannot load /usr/local/libexec/libphp4.so into server: Undefined symbol "_finite" in httpd:/usr/local/libexec/libphp4.so /usr/local/sbin/apachectl start: httpd could not be started pager# uname -a FreeBSD pager.fks.bt 2.2.6-RELEASE FreeBSD 2.2.6-RELEASE #0: Sun Oct 1 02:48:39 GMT 2000 root@claw.fks.bt:/usr/src/sys/compile/CLAW i386 I saw other people having similar problems with Unixware, but the patches in that case seemed to be Unixware specific. This is probably just a linking problem but I'm not familiar enough with the details of the PHP build process to determine the appropriate fix. I verified that the "finite" function in the math library exists and works. - Mike
