Summary: Compile of apache/php/mysql problem with missing symbols from zlib.

Hi, 

I got 2 replies, one was from Steve (ssandau@bath.tmac.com), who pointed out
that there was a new tool to control libraries, namely crle. I used this
tool to set the include path as well as the trusted library path to include
/usr/local. I also made sure that -lz was included by setting
EXTRA_LDFLAGS=-lz in <apache build dir>/src/Makefile. The second part would
have solved the problem I believe, as a version of libz.so (1.1.3) comes
with 2.8. However I forced the build to pickup the one from /usr/local/lib
created from the source. With those changes the make went to completion
Houston.
