[PHP-INSTALL] PHP 5.1.1 on linux, PDO MySQL problems

[Jerome]

After compiling PHP 5.1.1 (and 5.1.0 previously) myself on kubuntu 
linux, I can not used prepared statements with PDO & MySQL 4.1 that I 
have installed.  No results get returned, the same code on a windows XP 
machine with MySQL 4.1 and PHP 5.1 installed has no problems.  I can't 
figure out why this might be, something PHP needs that it doesn't 
explicitly say so just ends up breaking in behavior without?

My configure:
'./configure' '--with-apxs2=/usr/bin/apxs2' '--with-pdo-mysql' 
'--with-pdo' '--enable-trans-sid' '--enable-magic-quotes' 
'--enable-mbstring' '--with-regex=system' '--with-curl' '--with-mysql' 
'--with-mysqli' '--with-xml' '--with-xsl' '--enable-xsl' '--enable-soap' 
'--enable-sockets' '--with-zlib' '--with-gd' '--enable-gd'
