Mac RNA Folding software?

[John S. J. Anderson]

I'm looking for some RNA folding software for the Mac. I've found the
offerings on the ftp.bio.indiana.edu server, and they aren't able to do
what I want. I want to be able to fold _long_ RNAs, 1 or 2 kb in lenght. 

I've got access to GCG; is it possible to use some GCG functions to do this? 

I apoligize in advance if this is a FAQ; if it is, could somebody please
give me a pointer to the FAQ?

TIA...
