[Radiance-general] no gendaylit ???

[ZZ]

Dear all,

my operating system is Ubuntu8.04, and install radiance use
apt-get install radiance and apt-get install radiance-materials
I think the installed radiance should be 3.8version.
Most radiance commands work well, but I can't find "gendaylit"? and the
feedback information in command shell is"sh: no gendaylit found", then I
search the "gendaylit" in the "usr" folder, find nothing. could anybody tell
why that?

thank you in advance,
ragards,
ZZ
