Have you tried running convert-ly -ed on them?

Again: have you tried running convert-ly -ed on your files?  If you
didn't, it is not likely that your compile problems will _ever_
disappear without manual intervention.

And of course, there is always the option to send me the whole bunch of
your files and a paycheck in proportion to their size, and get a
conversion.  I try to make convert-ly as good as possible, so I probably
am cutting myself off from a nice regular revenue source, but there
_are_ problems that refuse an automatic conversion.
