Do not install executables by default?

On many systems, if you accidentally install PerlPowerTools many of the tools get broken.

While I love the idea of replicating UNIX tools written in pure perl, it sounds a bit too easy to accidentally break the system. Could you consider not install these executables by default without some options such as --install-executables are passed to configure script Makefile.PL?

Well, the point of Perl Power Tools is to install the executables. We'll have to come up with something to work around, this though, and lots of warnings in the docs.

I think perhaps they should be installed into a directory that is not in PATH and that people should have to add that new path to PATH themselves, and at the end of PATH.

Note that plenv and cpanminus still have the problem of finding an unsuitable tool. Someone who wanted to do something malicious merely needs to drop a program of the right name in a suitable spot.

Yeah that'd work for me as well. Thank you for considering the request!

In 1.005, I set INSTALL_BASE for the user and prompt them to set it themselves if they want something else. This should be good enough for the moment.
