Why does Perlbrew launch bash on Mac OS X Lion?

Question

When I run...

perlbrew switch perl-5.16.0

...I get...

A sub-shell is launched with perl-5.16.0 as the activated perl. Run \'exit\'

Answer 1

That happens when you have an improperly installed perlbrew. As part of the installation, you are instructed to add a command to your shell startup script, but that appears to be missing.

Add the following to your shell startup script:

source .../perlbrew/etc/bashrc

There's a similar script for csh.

source .../perlbrew/etc/cshrc
