For some reason, the installation creates the etc directory under the /usr/local/etc/sems/ :

make[2]: Entering directory `/usr/src/sems-1.6.0/apps/conf_auth'
mkdir -p **/usr/local/etc/sems/**etc**/**
installing conf_auth.conf
make[2]: Leaving directory `/usr/src/sems-1.6.0/apps/conf_auth'

Then at the make install ends the following is printed:

*** install complete. Run SEMS with 
*** 
***   /usr/local/sbin/sems -f /**usr/local/etc/sems/sems.conf**

At bottom libe, while following the spain document instructions, I figured out that the sems.conf wasn;t created at the /usr/local/etc/sems/ path.

I can create a new one or even copy this one found :
/usr/src/sems-1.6.0/apps/mobile_push/load_test/sems_cfg/core/etc/sems.conf
but I am afraid of further files/directory inconsistencies.

Any assistance is very appreciated.
