[xdebug-general] xdebug profiler not producing an output file

Hi all,

I can't get xdebug profiler to write to its output file on a centos
installation. It doesn't create the file. Here are the details.

O/S - Linux 2.6.18-8.1.15.el5 (centos)
Apache - 2.2.6
php - 5.2.5 (at least the client, this is the full php -v output)

[root[@]backup-prod-1 ~]# php -v

phpinfo settings related to xdebug (this is from a test.php that has
phpinfo() that i hit through the browser - not from executing the
cmdline php)

I have got this to work on my ubuntu desktop. But whatever i try, i
can't seem to make it work on this centos installation. BTW, I
followed instructions here for the xdebug install:

http://tech.nigel.in/

basically:
yum install php-devel
yum install gcc gcc-c++ autoconf automake
pecl install Xdebug

Any help much appreciated. I'm trying to debug a performance issue in
production, and it would be great to get the same xdebug data I get
when I run this sweet tool on ubuntu...

thanks,
