configuration problems

[<seagal bennjamin berlin de>]

Hi. I recive this message, when trying to run "make" in libgtop pack. I have an isdn-adapter, but I have never used it with linux. My box is a Slackware 7.1 with 2.4.5 kernel. 
So, that's the message:


O2 -Wall -Wunused -I/usr/X11R6/include
-DGTOPLOCALEDIR=\"/usr/local/share/locale\" -DLIBGTOP_VERSION=\"1.0.6\" -DLIBGTOP_SERVER_VERSION=\"5\" -DLIBGTOP_VERSION_CODE=1000006
-DLIBGTOP_SERVER=\"/usr/local/bin/libgtop_server\" -g -O2 -Wall -Wunused
-Wp,-MD,.deps/ppp.pp -c ppp.c  -fPIC -DPIC -o .libs/ppp.lo
ppp.c: In function `get_ISDN_stats':
ppp.c:58: `ISDN_MAX_CHANNELS' undeclared (first use in this function)
ppp.c:58: (Each undeclared identifier is reported only once
ppp.c:58: for each function it appears in.)
make[3]: *** [ppp.lo] Error 1
make[3]: Leaving directory `/gnom/libgtop-1.0.6/sysdeps/linux'
make[2]: *** [all-recursive] Error 1

make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/gnom/libgtop-1.0.6'
make: *** [all-recursive-am] Error 2

I tryed everything possible ... I insalled the isdn-adapter and it's funktional ( only the hardwear, not the ipppd protocol ). I installed enlightenment and it's working fine too.... I upgraded the whole network ( ppp and everything else ) But the ppp.c of libgtop is steel trying to find the device in the /dev/isdninfo ( I thing the last caontains data only when an isdn device is up )Actualy when the isdn device is up - the message is the same. 
I don't know what to do, please help.
