BAD! The libgea-package contains the POSIX version of GEA. You will need 
to install it to be able to compile GEA applications and if you like to 
run them outside of ns-2. So unpack, compile it in a separate directory. 
Copying on top of the ns-2/gea directory will overwrite the ns-2 version.

There is a prepare.pl script that you should prefer for this step.

OK (if outside of ns-2)

Should work if you do not overwrite it in step 3).

If this works, I will add this procedure to the nsnam wiki. There is no 
tutorial. You will find some examples in the test directory. For more 
background information read 
http://www-ivs.cs.uni-magdeburg.de/EuK/forschung/publikationen/pdf/2005/gea.pdf 
. Maybe I find some time to start a tutorial in the wiki.  

As a side notice - I just tried to compile gea with cygwin and gcc3.4.4 
and it failed because of problems with winsock2.h ... I will work on this.

Daniel.
