Installation errors

[muffato]

Hello,

I faced a few issues when trying to install baton on a fresh Ubuntu 18.04 container:

• Some Perl dependencies (for baton) are not declared in README or INSTALL: FindBin, JSON, List::AllUtils
• After make install, the binaries installed in /usr/local/bin were not able to find the .so, and I had to run an additional ldconfig /usr/local/lib/. I noticed that make install already runs ldconfig, but with the -n option. I think the problem is the same as https://github.com/esnet/iperf/issues/153#issuecomment-42897883

Best, Matthieu

Closed with a workaround of running ldconfig separately (this is what we do e.g. in Dockerfiles). Folding it into the Makefile affects non-root users
