-------------------------+--------------------------------
 I've used `py27-numpy @1.7.1_0+atlas+gcc47` since mid April with no
 problems. After I forced an upgrade a couple days ago I get this traceback
 when I import numpy:

 {{{

 This library has the missing symbol:
 {{{
 $ nm /opt47/local/lib/gcc47/libgcc_s.1.dylib | grep restGPRx
 00005f98 t restGPRx
 }}}
 but `multiarray.so` does not link with it:
 {{{

 version 1.0.0)

 version 111.1.7)
 }}}

 I noted in the log file that `gcc-4.0` is used to create the extension
 libraries (but the source is compiled with `gcc-mp-4.7`). I have the `port
 -d` output from the April build of numpy, and it confirms that the
 extension libraries were built with `gcc-mp-4.7`, not `gcc-4.0`, at that
 time.

 I've attached the log file from the recent build of numpy.
