Snort 'make install' error on Linux

Question

I'm trying to install Snort on Debian and I get this error after 'make install':

make[6]: Nothing to be done for 'install-exec-am'.
 /bin/mkdir -p '/usr/local/lib/snort_dynamicengine'

What am I missing here?

Adding 'sudo' before the command did the job.

sudo make install
