Comment (by ryandesign):

 cdrtools is part of the [http://schilytools.sourceforge.net schily
 collection of tools], along with its build system smake, which has a
 similar problem. (I could not begin to troubleshoot the cdrtools problem
 without first building smake, which I could not build for the same
 reason.) I don't intend to attempt to fix it myself due to the complexity
 of the way that this developer implements his projects. I have
 [https://sourceforge.net/p/schilytools/tickets/25/ reported the smake
 problem] to him with no response yet.
