Help compiling zaptel

Trying to install the latest drivers

I am at zaptel section .
./configure ->OK
make -> OK
make install ->OK
make config I get the next message.

/usr/bin/ginstall -c -D -m 644 zaptel.sysconfig /etc/default/zaptel
zaptel defaults 15 30
make: zaptel: Command not found
make: *** [config] Error 127

My system is Slackware 12.0 and zaptel driver 1.4.6 .

Igoring this message and runnig modprobe zaptel I get this message

FATAL: Module zaptel not found.

Ignoring this message too, I configured zaptel.conf and zapata.conf , but when I run ztcfg -vv I get this message .

root@koukouroukou:/usr/src/zaptel-1.4.6# ztcfg -vv
Notice: Configuration file is /etc/zaptel.conf
line 0: Unable to open master device ‘/dev/zap/ctl’

1 error(s) detected

So what is wrong ? What am I making wrong ?

Thank you . Please need help .
