Zaptel install freaky error

I kept getting this error. Im on centos and I already download the necessary dependencies. I even have the kernel-devel and stuff

[root@rheeka zaptel-]# make clean
grep: /include/linux/autoconf.h: No such file or directory
rm -f torisatool makefw tor2fw.h radfw.h
rm -f ztcfg torisatool makefw ztmonitor ztspeed zttest fxotune
rm -f *.o ztcfg tzdriver sethdlc sethdlc-new
rm -f zonedata.lo tonezone.lo *.lo
make -C SUBDIRS=/usr/src/zaptel- clean
make: *** SUBDIRS=/usr/src/zaptel- No such file or directory. Stop.
make: *** [clean] Error 2

any help and hints is highly appreciated.

did you search the forum for “autoconf.h” ?
