perlbrew ignoring minor version upgrade

Question

I am using perlbrew (App::perlbrew/0.67) on OS X 10.9

If I list the current installed Perl versions I get

$ perlbrew list
* perl-5.18.1 (5.18.2)
$ perl --version

This is perl 5, version 18, subversion 2

So it seems that I have version 5.18.2 installed but listed as 5.18.1 (with the correct number in brackets)

$ perlbrew available
perl-5.19.11
perl-5.18.2
perl-5.16.3
...

perlbrew available is listing 5.18.2 (with 2). Is this normal or do I have a broken installation? Why does list show two versions (--help and the manual on CPAN do not show any hint).

Maybe you have multiple versions of perl installed, it's not that uncommon. Check all your include paths and see if any of them lead to different versions — Analog, May 13 '14 at 11:46
Looks to me like you did a `perlbrew install` of 5.18.1 and then did a `perlbrew upgrade-perl` to that install when 5.18.2 was current. Don't be concerned about `perlbrew available`, it's just listing what's sitting on the server for convenient download... — tjd, May 13 '14 at 12:33
@ikegami I get it now. It's the name and the version in parenthesis. I installed 5.18.1 and named it 5.18.1 and then updated it ... — Matteo, May 13 '14 at 13:08

perl-5.18.1 is just an arbitrary name. You sure picked a weird one for an install of 5.18.2!

This is my list on one machine:

  5.8.9                  # 5.8.9
  5.8.9d                 # Debugging build of 5.8.9
  5.14.2                 # 5.14.2
  feed_fetcher (5.14.2)  # Used by specific project
  5.16.3t                # Threaded build of 5.16.3
* 5.18.0t                # Threaded build of 5.18.0
  latest (5.18.0)        # An (outdated) alias

Unfortunately, you can't fix this by simply renaming the directory. You can do perlbrew install 5.18.2 to install 5.18.2 as 5.18.2, make sure it works, then delete $PERLBREW_ROOT/perls/5.18.1.

If you plan on upgrading a build using upgrade-perl, create it as follows:

perlbrew install --as 5.18 5.18.0

You'd switch to that install using

perlbrew use 5.18        # This shell only
perlbrew switch 5.18     # Switch default

That way, the name will still make sense after you issue perlbrew upgrade-perl.
