include zvt/zvtterm.h problem

[cuichun <asdf2970 21cn com>]

hi,all!
I have a problem, please help me!thx
How can I include /usr/include/gnome-1.0/zvt/zvtterm.h into my program.
after I run the command:
gcc prog.c -o prog `pkg-config --cflags --libs gtk+-2.0 zvt`

and got this error:
...zvt/zvtterm.h: No such file or directory

I am sure that I install the gnome-libs-devel
