Installing perlbrew: Failed to retrieve patchperl executable

Question 1

Or you can disable certificate checking. The following worked fine for me:

echo "check-certificate = off" >> ~/.wgetrc

perlbrew install-patchperl
perlbrew install-cpanm

Happy brewing!

Question 2

Perlbrew installs cleanly for me (also on Mac OS X 10.9.1).

There is an issue report (here) that it is worth you reading through. It seems likely to be an issue with your version of cURL coupled with GitHub HTTPS URLs. There are a couple of things worth trying:

curl -kL http://install.perlbrew.pl | bash
(-k allows insecure SSL connections)

Install patchperl manually:

curl -kL https://raw.github.com/gugod/patchperl-packing/master/patchperl > ~/perl5/perlbrew/bin/patchperl`

Question 3

Based on a suggestion of @jm666, I tracked down the problem source (at least one of them).

What I did:

Removed perlbrew: rm -rf ~/perl5/* ~/.perlbrew
Completely removed macports
Installed a fresh macports package

And I tried installing my usual MacPorts and after every installed port, started a new terminal/shell and tried installing perlbrew.

After I installed the wget port, the perlbrew installation failed (installing the patchperl). After uninstalling the wget port, perlbrew installed again OK.

For the log, installing wget:

## Download the latest perlbrew

## Installing perlbrew
perlbrew is installed: ~/perl5/perlbrew/bin/perlbrew

perlbrew root (~/perl5/perlbrew) is initialized.

Append the following piece of code to the end of your ~/.bash_profile and start a
new shell, perlbrew should be up and fully functional from there:

    source ~/perl5/perlbrew/etc/bashrc

Simply run `perlbrew` for usage details.

Happy brewing!

## Installing patchperl

## Done.

Conclusion: Something go wrong with a combination of MacPorts' wget and perlbrew.

Question 4

Check your PATH order. Watch out for macports PATHs getting added later to the search than the perlbrew paths. I just cleaned out a bunch of "helper" addenda PATHs in .bash_profile, .profile and put everything in .bashrc, in the order in which I want to search, i.e. perlbrew before macports before system. If you are left joining your path, i.e. PATH=/foo:/bar:$PATH, go in reverse order in your start up file than you want the search path to accrue. Below I add the macports /opt/local/bin:/opt/local/sbin to the path before the perlbrew path elements.

Question 5

For me it helped changing the PATH environment variable - disable MacPorts by commenting out the next line.

export PATH=/opt/local/bin:/opt/local/sbin:$PATH

or similar in your ~/.profile.

Something doesn't play nicely from the MacPorts binaries in /opt/local/bin with perlbrew.

For example, with enabled macports, for the

perlbrew self-upgrade

you will get

Unable to detect version of new perlbrew!

with disabled macports in a PATH will get correctly:

Your perlbrew is up-to-date.

and like.

After installing perlbrew, and your perlbrew's version of Perl and (ofc) sourcing the perlberw's bashrc you can return the PATH - only don't forget comment out every time when you want use perlbrew itself. And the

source ~/perl5/perlbrew/etc/bashrc

should be after the macports PATH setting.

At least, on my installation - maybe your problem has another roots...
