MrSID in IDL [message #81780]

I'm trying to open a MrSID file in IDL--there shouldn't be anything complicated about it. There are a couple of ways of doing so, but neither one seems to be working.

First, I try something simple like the following:
fileInfo = QUERY_MRSID("/volumes/data/files/GRWD/Misc/N-06-60.sid")
And I get the following error:
% Variable is undefined: QUERY_MRSID

Then, I try the other (object-oriented) method:
Result = OBJ_NEW('IDLffMrSID', "/volumes/data/files/GRWD/Misc/N-06-60.sid")
And I get the following error:
OBJ_NEW: Dynamically loadable module is unavailable on this platform: MRSID.

I've tried this on a Mac (OS 10.6.8) and on a PC (Windows 7), using IDL 7.1, 8.0, and 8.2.1. Exactly the same errors. I've also tried it using the sample .sid file that is provided with IDL. Same result, using exactly the same code that's in the help documents (with file path changed appropriately).

Any idea what might be going on?

Thanks in advance,
Tamlin
