Build DAHDi from Source w/ DKMS

I’m having a hard time figuring out how to install DAHDi from Source using DKMS on CentOS; this is what I’m doing…

cd /usr/src/dahdi-linux-3.1.0
make clean && make && build_tools/dkms-helper add

( ‘dkms status’ shows dahdi-linux 3.1.0 is installed successfully on the current kernel )

cd /usr/src/dahdi-tools-3.1.0
autoreconf -i
automake --add-missing
./configure --libdir=/usr/lib64 && make && make install && make install-config

DAHDi Tools ‘make’ is generating error:
configure: *** Building this package requires DAHDI support. ***
configure: *** Please install the dahdi-linux package. ***

…not sure what I’m missing; can someone help?

Thank you!

git clone -b next
cd dahdi-linux
make install
That’s all.
