>Environment:
Minix 192.168.122.210 3.2.0 i686
>Description:
games/cmatrix can use ncurses or curses for displaying it's
character waterfall. Without ncurses, it fails to build on
Minix. Additionally, the cmatrix README says "You'll probably
need a decent ncurses library to get this to work."
The patch below adds an ncurses option to the cmatrix package.
>How-To-Repeat:
On a Minix system without ncurses do this:

# cd /usr/pkgsrc/games/cmatrix && bmake install
...
gcc -DHAVE_CONFIG_H -I. -I. -I.   -D_MINIX -D_POSIX_SOURCE 
-I/usr/pkg/gcc44/include -I/usr/pkg/gcc44/lib/gcc/i386-pc-minix/4.4.5/include  
-Wno-error -I/usr/pkg/gcc44/include 
-I/usr/pkg/gcc44/lib/gcc/i386-pc-minix/4.4.5/include -Wall -Wno-comment -c
