Tailing cpanm build logfile

When using tools like cpanm want to be able to tail the log file generated for build. cpanm offers a canonical log file at: $HOME/.cpanm/build.log in addition to the temporary log files located in the $HOME/.cpanm/work/* directories.

But the $HOME/.cpanm/build.log changes with every build, so tail -f $HOME/.cpanm/build.log falls short.

So the tip is to use tail -F $HOME/.cpanm/build.log instead.
