Unfortunately the situation is even worse than simply disc-cover (or p5-Audio-CD's) inability to read CDs. Even if one fudges things and manually feeds it a CDDB entry (via the -f flag), the TeX file generated fails to compile under latex correctly, and so the program barfs, deleting the temporary .tex file created. This happens under both teTeX and texLive. One then has to use the "-t tex" flag to get it to output a .tex file without running latex. Manually fixing the .tex file is relatively simple (one simply needs to remove the "isolatin1" flag located in the first 2 or 3 lines), but all this messing around does suggest that it's been a long time since anyone used this port (and, possibly, a long time since anyone used p5-Audio-CD). I'd suggest that removing this port from 4.2 is unlikely to effect anyone, and it will save us from an unused, buggy, program being in the ports tree.
