Missing builder.h in gtkmm-2.4

[Ming-ching Chiu <percle gmail com>]

I've been working on gtkmm project on Ubuntu and things run pretty smoothly. Recently I'm trying to compile my code in a CentOS machine.

I'm pretty sure i installed Gtk and gtkmm on the CentOS machine because the "hello world" program compiles and runs on CentOS.

(I installed the packages in the RPMforge).


However, when I tried to compile my project. the compiler complains that " Builder is not a member of Gtk".

I then checked the files listed in /usr/include/gtkmm-2.4/gtkmm/  in both computers and figured that the directory in my CentOS system has fewer files than the one in Ubuntu. And of course, "builder.h" is missing in CentOS too.

Has anybody seen this problem?  My CentOS is  CentOS 5.4    x86_64 version
