#279: Compiling with Mac OS and Intel compiler leads to missing library warning
--------------------+-------------------------------------------------------
 Reporter:  hinder  |        Type:  defect
   Status:  new     |    Priority:  minor 
Milestone:          |   Component:  Cactus
  Version:          |    Keywords:        
--------------------+-------------------------------------------------------
 When I compile Cactus with the Intel compiler on Mac OS I get the
 following warning at link time:

   ld: warning: directory '/opt/intel/Compiler/11.1/084/bin/lib' following
 -L not found

 I traced this to the known_architectures/darwin file which guesses the
 location of the library directory relative to the output of $(which
 ifort).  I think now that newer compilers have 32 bit and 64 bit versions
 under different directories, the directory layout has changed and the
 guess is now wrong.  The warning appears to be harmless, but it is
 annoying.  The attached patch checks to see if the first guess directory
 exists, and if it doesn't, it looks one level higher up.  On my system
 this guess is correct and the warning message is eliminated.  I looked at
 the corresponding logic in the linux file but maybe the directory layout
 is different on Linux.
