[Radiance-daysim] DAysim_warning message

[Jan Wienold]

it seems you are using an old version of gendaylit (the new version don 
t need these files any more). Maybe this old version is still part of 
the daysim package. You should replace it by the new version from the 
radiance distribution.
I also assume you have a path problem. Are you sure you set the RAYPATH 
variable correct? In the /lib directory you should find the missing 
files, but then the old version of gendaylit should work.
