       Type:  defect    |      Status:  new       
   Priority:  major     |   Milestone:  sage-4.3.1
  Component:  porting   |    Keywords:            
Work_issues:            |      Author:

     Merged:            |  
------------------------+---------------------------------------------------
 The spkg-install of libz zlib-1.2.3.p5 has this:

 {{{
 if [ `uname` = "Darwin" -a "$SAGE64" = "yes" ]; then
    CFLAGS=" -m64 $CFLAGS -fPIC -g -I\"$SAGE_LOCAL/include\""
    cp ../patches/configure-OSX-64 configure
 else
    CFLAGS="$CFLAGS -fPIC -g -I\"$SAGE_LOCAL/include\""
 fi
 export CFLAGS
 }}}

 so is almost doomed to a 64-bit build unless one sets CFLAGS externally.
