I realize it's for CentOS 6 but I was hoping it might carry over. Is there an updated guide for 7?

I just installed "CentOS-7.0-1406-x86_64-Everything" on a Dell D630 which has a Broadcom 1390 WLAN MiniCard
According to the readme it might be a supported device
This step is where I'm hung up
[Joe@localhost hybrid-wl]$ make -C /lib/modules/`uname -r`/build/ M=`pwd`
make: *** /lib/modules/3.10.0-123.el7.x86_64/build/: No such file or directory. Stop.
[Joe@localhost hybrid-wl]$ ls /lib/modules/`uname -r`/build
/lib/modules/3.10.0-123.el7.x86_64/build
I've made sure there were no missing packages and ran yum install kernel-devel again just to make sure.
Joe@localhost hybrid-wl]$ lspci | grep Broadcom

Any help would be greatly appreciated. Thanks in advance!
