Erro ao compilar Source

[Steve Rogers 3]

Boas...

Estou tentando compilar o game, mas quando tento me dá esse erro:

 

root@Mt2Source:/usr/src/Server/game/src # gmake
linking ../game_r41026
/usr/local/bin/ld: cannot find -lthecore
/usr/local/bin/ld: cannot find -lpoly
/usr/local/bin/ld: cannot find -lsql
/usr/local/bin/ld: cannot find -lgame
/usr/local/bin/ld: cannot find -lserverkey
collect2: error: ld returned 1 exit status
gmake: *** [Makefile:196: ../game_r41026] Error 1
root@Mt2Source:/usr/src/Server/game/src #

Os diretórios "libthecore", "libpoly", "libsql", "libgame" e "libserverkey" estão em  "/usr/src/Server"

Este é o "Makefile" do game:
