flexfax: Problem installing HylaFAX at Slackware 3.5

["KREMMIDAS KLEANTHIS" <kremidas@lrf.gr>]

Hello to all,

I'm trying to install HylaFAX 4.0 pl2 on my Slackware machine with 
kernel 2.0.34.
The output from gcc -v follows:
#Reading specs from /usr/lib/gcc-lib/i586-pc-linux-gnulibc1/egcs-
2.90.29/specs
gcc version egcs-2.90.29 980515 (egcs-1.0.3 release)

The problem seems that the sendfax program cannot be compiled 
since faxsetup cannot find it and at the compilation an error is 
produced. 
Could someone help me please cause it is something very 
important. What should I do ?? 

Thank you in advance.
