Bootstrap error

[Douglas B. Staple]

Hey Jonathan,

Thanks for the ideas. I tried:
1) removing the '-j 16'
2) using an absolute path when calling configure.
3) using the contrib/download_prerequisites script to download 
mpfr-2.4.2, gmp-4.3.2, and mpc-0.8.1, instead of the newer versions above.
4) setting the PWDCMD environment variable to an automounter-aware pwd 
command (pawd).

None of these things resolved the issue.  I'm out of ideas for now, so I 
posted the question on Super User:
http://superuser.com/questions/592552/bootstrap-error-while-compiling-gcc-4-8-0
If the answer comes up here then I'll post it there and vice versa.

Doug
