It doesn't know where this file is - probably because it is in a
folder IDL doesn't know about. IDL has a list of directories that it
looks for whenever trying to read or run anything (this is also how
you get around manually compiling all of these files -IDL
automatically looks in these folders and will automatically compile
the code it needs to if it can find it). I have an older version of
IDL, but there should be something like edit->preferences in IDL.
Then, find the tab called 'path', choose to add a new directory to the
path, and then add in all of the folders where you keep IDL code or
files you want IDL to read. Then, things should compile and read much
more easily. Note, you should be able to check a box that searches in
all of the subdirectories of a given folder as well.
Once you set up these paths, go ahead and dump the ENTIRE IDL astro
library in one of the folders in your path. Then, you never need to
worry about compiling them again.
