SYSTEM REQUIREMENTS: 

rTANDEM uses 'expat' and 'pthread' libraries. Their avalability might vary according to operating system.

expat:
The expat library should be available on OSX since 10.4.
The expat library for linux can be downloaded at http://sourceforge.net/projects/expat/files. 
The expat library for Windows can be downloaded at http://sourceforge.net/projects/expat/files. 

pthread:
The pthread library should be available on OSX since 10.3.
The pthread library is available on most linux plateforms.
A version of pthread is available for win-32 and can be downloaded at http://sourceware.org/pthreads-win32.

When building from sources on Windows systems, linking against the expat library can be problematic. To circumvent this difficulty, create a directory structure like this one: 
C:\expat\i386
C:\expat\x64
Then place the 32 bit and 64 bits libraries respectively in C:\expat\i386\lib and C:\expat\x64\lib. Finally, create an environment variable LIB_EXPAT and set it to "C:/expat/". This should allow the build process to sucessfully link against the expat libraries.
