Change the path of SYSTEMD_UNITDIR from  /lib/systemd/system to

Hello, 

I have problems to create the rpm file with the make rpm command on my Fedora 19. 

I receive this error : 


RPM build errors:
    File not found: /home/ataliba/rpmbuild/BUILDROOT/zram-1.0.0-0.fc19.x86_64/usr/lib/systemd/system/zram.service
make: *** [rpm] Error 1
[ataliba@neo FedoraZram]$ vim Makefile 

Reading the Makefile i see an problem because the /lib on Fedora 19 is a symbolic link to /usr/lib 
I change the variable SYSTEMD_UNITDIR to  /usr/lib/systemd/system

and the command make rpm runs without problems.
