Apache & PHP4 won't play together

[Kevin Krumwiede <kjkrum@comcast.net>]

I'm using 3.0r2 on sparc.  I installed apache and php4 via apt-get. 
Apache refuses to start with the following line uncommented in
httpd.conf:

# LoadModule php4_module /usr/lib/apache/1.3/libphp4.so

Package versions are apache 1.3.26-0woody3 and php4 4.1.2-6woody3.

Others have described exactly the same problem, on various
architectures:

Any solutions?  Please cc me.
