Trouble getting PHP installed to use with acid

["Cessna, Michael" <MCessna () rtm com>]

I'm hoping someone here can help me with this:
When trying to compile php4 into apache to use with acid I'm getting the
following error:
./compile --activate-module=src/modules/php4/libphp4.a

my_compress.o(.text+0x12a): undefined reference to 'compress'
collect2: ld returned 1 exit status
make[2]: *** [target_static] Error 1
make[2]: Leaving directory '/root/apache_1.3.20/src'
make[1]: *** [build-std] Error 2
make[1]: Leaving directory '/root/apache_1.3.20/src'
make[1]: *** [build] Error 2

Any help would be greatly appreciated. I am a *nix beginner and can't figure
out what's going on here.
Thanks in advance
