As I suspected, those are linker errors! That means steps 1 and 2 worked. Now 
(step 3), you need to specify the directory where to find the boost libraries, 
as well as the lirbary file(s) for the linker to link with. At this point you 
have plenty of choices: static/dynamic, multi-thread or not, debug/release.

3a) You might have some of the following library files in your AIX 
[...]/boost/lib directory:

boost_filesystem-AIX-mt-1_31.so
boost_filesystem-AIX-mt-1_31.lib
boost_filesystem-AIX-mt-gd-1_31.so
boost_filesystem-AIX-mt-gd-1_31.lib

On your compiler command line, add "-L /usr/local/include/boost-1_32/boost/lib" 
(or make a symbolic link as you did for the include directory 
towards /usr/local/include/boost/lib and use this one instead, as you wish).

Then (usually at the end of the command line) add the library file you like. 
May I the a static one (.lib). Your command line should look like:

xlc++ -o simple_ls simple_ls.cpp -I /usr/local/include -
L /usr/local/include/boost-1_32/boost/lib boost_filesystem-AIX-mt-1_31.lib

Ignore the makefile since you're using the command line directly.

3b) On MSDEV6, 

i) add "libboost_filesystem-vc6-sgd-1_32.lib" in your project settings. More 
specifically in the "Link" tab, under "Input" category (drop-down list), and 
at "Object/Library modules:".

ii) and add "c:\boost\include\boost-1_32\boost\lib" in "Additional library 
path:".

It should work.
