#13436: LD_PREBIND and LD_PREBIND_ALLOW_OVERLAP harmful on 10.5

     Type:  defect                                    |      Status:  new                
 Priority:  High                                      |   Milestone:  MacPorts 1.6       
Component:  base                                      |     Version:  1.5.2              
 Keywords:  LD_PREBIND LD_PREBIND_ALLOW_OVERLAP 10.5  |  
------------------------------------------------------+---------------------
 Setting LD_PREBIND and LD_PREBIND_ALLOW_OVERLAP to "1" results in build
 errors on various ports in Mac OS X 10.5 which fail with {{{ld: symbol(s)
 not found ...}}};
 e.g. the postgresql ports fail to compile (#12994

 Could we remove this feature for the 1.6 release? (or make it OS dependant
 or configurable? Does it make sense on 10.5 at all?)
