[Linux] Game unable to start with error gtk_widget_get_realized

Hey guys,

I absolutly love your game and I would like to run in on my laptop which is using RHEL 6.4 as OS. Whenever I am trying to run the game I am getting this error message

/opt/greenheartgames/gamedevtycoon: symbol lookup error: /opt/greenheartgames/gamedevtycoon: undefined symbol: gtk_widget_get_realized

I presume that I am missing some libraries, but I lack the knowladge to fix it my self.
Thanks for letting me know what I am doing wrong.

Update:

uname -a
Linux XXX 2.6.32-358.6.1.el6.x86_64 #1 SMP Fri Mar 29 16:51:51 EDT 2013 x86_64 x86_64 x86_64 GNU/Linux

Same.

Running CentOS 6.4.

What version of GTK are you guys running?
