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' to finish it.` ...then a bash prompt appears. Is this expected behavior? If not, how can I fix it?

Accepted Answer

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
```
