in kdevelop adding both enlightenment-config and edje-config libs and cflags I get the same results:

while with the command line gcc e_mod_main.c `enlightenment-config --libs --cflags` I get: /opt/e17/include/enlightenment/e.h:7:20: error: config.h:/opt/e17/include/enlightenment/e.h:7:20: error: config.h:not such file or dir
