After installing warsow from ports on FreeBSD 8.2/AMD64, got some issues:

# cd /usr/ports/games/warsow
# make config
# make install clean 

wsw_server

- angel script initialization -
Loading angelwrap module.
Loading angelwrap failed

Fix: Looks like angelwrap library is missing in my system
Then i try to compile game and angelwrap library from source

# cd /usr/ports/distfiles/warsow/source
# gmake game

Then I found  some  patches 

# cd /usr/ports/games/warsow/work/libsrcs/angelscript/angelSVN/sdk/angelscript/source

# fetch ftp://ftp2.za.freebsd.org/pub/FreeBSD/ports/games/rigsofrods/files/patch-dependencies-angelscript-source-as_config.h

After some editing patch files:

# patch <patch-dependencies-angelscript-source-as_thread.h
# patch <patch-dependencies-angelscript-source-as_config.h
# patch <patch-dependencies-angelscript-source-as_thread.cpp

Now return to build angelwrap
# cd /usr/ports/games/warsow/work/source
# gmake angelwrap
# gmake game
# gmake ded

When i ran wsw_server
