No. I tried googling it, and came up empty. The standard Arduino SD library contains a macro PgmPrint in SdFatUtil.h, but I found no PgmPrint.h files.
Even if you comment out the #include 'pgmPrint.h", the sketch still has problems.
The WaveRP library was written by Bill Greiman, who checks in here frequently. Maybe he can suggest what it is we're missing.
