apache+ssl+mod_php4 - is it possible?

[null]

Greetings,
 I can't seem to get apache13+ssl to build from source. It dies with
"libm.so.2 can't
be found". If I install it by package from /stand/sysinstall it will
install fine. But then
I am unable to add mod_php4 or any other mod_*. I checked this system and
one other
5.4 system I have and libm.so.* does not exist. The system in question is an:
i386 running 5.4-RC1. Thank you for all your time and consideration in
this matter.

Sincerely,
 Chris
