PHP 5.2.3 cannot compile on CentOS-5

[Ben <elbekko@xxxxxxxxx>]

Hello,

I'm trying to compile PHP 5.2.3 from source on CentOS-5. Configure went 
fine, but when running make I get the following error:

/usr/bin/ld: cannot find -lintl
collect2: ld returned 1 exit status
make: *** [libphp5.la] Error 1

Yet the intl package has been installed:

# rpm -qa | grep intl
intltool-0.35.0-2

Does anybody have any idea on how to fix this?

Thanks,
Ben
