Comment (by stephen at xemacs.org):

 > Looks like there was possibly something 'interesting' happening with

 Unlikely; this only happens with "apr" that I have seen so far.  I
 successfully built GCC 4.3.1 after observing it the first time, and before
 running "port -d upgrade apr".

 > Are you able to consistently reproduce this?

 Sure.  This time with a sledgehammer:
