Installing PHP5 on x64 OpenSuSE 10.2

Hi.

I'm having to do a manual install of PHP5 on a OpenSuSE 10.2 box running 
Cpanel as they do not seem to support this version properly and the auto 
update for PHP does not appear to work properly.

I'm having real issues seemingly down to the fact it is a 64bit version 
running.

the configure line:

./configure --prefix=/usr/local/php5 --datadir=/usr/local/share/php5 
--with-libdir=lib64 --enable-libxml --enable-session --with-mm 
--with-pcre-regex --enable-xml --enable-simplexml --enable-spl 
--enable-filter --disable-debug --enable-inline-optimization 
--disable-rpath --disable-static --enable-shared  --with-pic 
--with-apxs=/usr/local/apache/bin/apxs  --disable-cli --with-mysql 
--with-openssl --without-iconv

It fails just after checking for mysql_errno suggesting I add the line 
to specify a path to the zlib dir, however the config.log suggests 
something completely different:

I tried other variations, such as adding the zlib support (which I do 
need anyway) but it then fails claiming I need zlib>1.0.9, which I do 
have (zlib 1.2.3) including all devel files.  The thing is, it fails on 
another test compile again with the "cannot find -lm".  I presume this 
is the "libm.so" library, which I have in both /lib64 and /usr/lib64.

I have googled and found others with similar problems trying to compile 
PHP on an x64 system, but haven't found an answer for this specific issue.

Any ideas??

Thanks
