Problems with make menuconfig

[Michael Kirchner]

i can't start make menuconfig.
I get the errormessages:
dialog.h:29: curses.h:  No such file or directory
make[1] *** [lxdialog.o] Error 1
make[1] Leaving directory 
'/usr/scr/kernel-source-2.0.34/scripts/lxdialog'
make: *** [menuconfig] Error 2
Does anybody knows the solutions for the problem.
thank you in advance
