misc/screen doesn't work on netbsd-5

Hi,

misc/screen is broken on netbsd-5. On both macppc and amd64, screen just 
returns "Abort".

Not directly related, but while compiling, I kept seeing attempts to run 
git:

cc -c -I. -I.  -I/usr/include -DETCSCREENRC='"/usr/local/etc/screenrc"' 
-DSCREENENCODINGS='"/usr/local/share/screen/utf8encodings"' 
-DHAVE_CONFIG_H -DGIT_REV=\""`git describe --always 2>/dev/null`"\"   -O2 
-I/usr/include viewport.c
git: not found

Why wouldn't the git version be assigned to a variable rather than run a 
whole bunch of times?

Thanks,
John
