LinuxQuestions.org - Trouble installing wine

I'm running Fedora 19 and am using this guide to try to install wine:

http://www.tecmint.com/install-wine-...os-and-fedora/

I'm stuck on step 4. When I enter this in terminal: ./tools/wineinstall

I get this:

Wine Installer v1.0

We need to install Wine as the root user. Do you want us to build Wine,
'su root' and install Wine? Enter 'no' to build Wine without installing:
(yes/no) yes

Configure failed, aborting install.

Where do I get this flex package? I've googled this, and have so far only found flex packages for Ubuntu. I don't want to download the wrong one.

My system is 32-bit, btw.
