errors with runing make install

I'm trying to install tvark on suse 9.1. The install files says to run make install from the directory that its unarchived in. I have done that an made sure that i have the required software installed on the machine as far as I know. i'm getting the following erros when i run make install: dualcpu:/tvark/tvark-0.4 # make install cc `gtk-config --cflags` -ggdb -I/usr/include/pcap -DBINDIR="\"/usr/local/bin\"" -c -o db.o db.c /bin/sh: line 1: gtk-config: command not found /bin/sh: line 1: cc: command not found make: *** [db.o] Error 127 Being that first time I have ever used make to install something was wondering if anyone knows what to make of the above error. thanks. jack
