I tried to install php 4.4.0dev with Apache 2.0.43 by doing:

./configure --with-apxs2=/usr/local/apache2/bin/apxs --with-pgsql
make

and got:

ld: can't locate file for: -laprutil

I deduced from bug reports on other OS that my be this file
was not necessary, and removed "-laprutil" from the makefile.
Then, make goes further, with similar problems.
You will find below the diff between the original Makefile
and the final. With this, make achieve its goal, and php
seems to work, and to connect to the pgsql server through
my browser. 
However, ld produced a lot of warnings about multiple
definition

ld: warning multiple definitions of symbol _XmlInitEncodingNS
ext/xml/expat/xmltok.o definition of _XmlInitEncodingNS in section (__TEXT,__text)
/usr/local/apache2/bin/httpd definition of _XmlInitEncodingNS

and lot of others. Is there any problems with this ?


Here is the diff :
