 On many Linux boxes, building the frobby-0.7.6 spkg fails as follows:

 {{{
 gcc version 4.4.1 (Ubuntu 4.4.1-4ubuntu8)

 sage: An error occurred while installing frobby-0.7.6
 }}}

 I ran the command "sage -i frobby-0.7.6" on the build farm and it fails
 on:

   * debian32/64
   * fedora32/64
   * mandriva32/64
   * opensuse32/64
   * ubuntu32/64

 It works on centos (=REDHAT).    It works on sage.math.   Basically it
 works with gcc <= 4.2 and fails with newer GCC's.
