Comment (by John Willis):

 I had this same issue. I traced the problem to the fact that line 862
 mentioned in the ticket has a bug in the call `next(i for i, field in
 enumerate(fields) if field.startswith('rtems))`

 This causes a stop iteration when the generator, on which we are calling
 next, is empty. In my case, the directory being searched for files ending
 in `.pc` and starting with `rtems` consists of :

 ./rtems/6/lib/pkgconfig/sparc-rtems6-erc32.pc
 ./rtems/6/lib/pkgconfig/gmp.pc
 ./rtems/6/lib/pkgconfig/expat.pc
 ./rtems/6/lib/pkgconfig/sparc-rtems6-leon3.pc

 when the function gets to "gmp.pc" or "expat.pc", it will fail with a
 StopIteration because we are calling "next" on an empty generator.
