Here's an update: I checked the ChangeLog for R, and it seems like readDCF was changed in 3.0.2. I went on a whim and copied src/main/dcf.c from R 2.15.3 over to 3.2.2, and R compiled fine and install.packages now work for me.
This is probably not ideal, but it at least makes R usable on AIX for me. Would definitely like to help figure out what's wrong with the new dcf.c on AIX.
