OpenKiosk multi-platform kiosk framework

I'm trying to install OpenKiosk on my CentOS 5.2 system, but I get as far
as...

[root@tiger ~]# cd /data_1/software/openkiosk/OpenKiosk
[root@tiger OpenKiosk]# cd xlobject/src/; make
ar cqs libxl.a baseobject.o xlsocket.o xlserversocket.o xlthread.o
g++ -pipe -Wall -O2 -pg -I./ -o nettest test.cpp -lxl -L./ -lpthread
g++ -pipe -Wall -O2 -pg -I./ -o simple simple.cpp -lxl -L./
g++: simple.cpp: No such file or directory
make: *** [simple] Error 1
[root@tiger src]#

Could you help me with what is probably a very simple problem?
