Again, filing this issue based on discussion in #555. Currently Truffle doesn't support Solidity <0.4.9 because the (wrapped) compiler output doesn't give file paths, but rather just groups every contract under the empty path. Over on #555, @cameel suggested it might be possible for solc/wrapper to repair this? I certainly hadn't considered that possibility! Well, just in case it is, I'm filing this issue as suggested. :)
