How can I control the Perl version I want?

[Jeremy Lavergne]

The big take aways here are:
* the perl5 port currently controls the perl symlink
* to specify a specific 5.xversionn the variants must be used
* variants are specified by +xxxx

Thanks to All of you...
So issuing the command:

sudo port install perl5 +perl5_14

solved the issue

However I did uninstall all Perl versions first (--following-dependents) and start reinstalling Perl5 +perl5_14 and then install the other ports (just to make me feel better and to punish myself for my mistake...;)

Now when I issue, I get:

==

# which perl
/opt/local/bin/perl

==

# port installed perl5
The following ports are currently installed:
  perl5 @5.12.3_1+perl5_14 (active)

==

# ls -l /opt/local/bin/perl
lrwxr-xr-x 1 root admin 8 Jan  5 13:32 /opt/local/bin/perl -> perl5.14*

==

# perl --version

This is perl 5, version 14, subversion 1 (v5.14.1) built for darwin-thread-multi-2level

Wouldn't perl need to be installed as "perl5 +perl5_14" not "perl5 @5.14.1_2"?

The default is activated by the variant given to the perl5 pseudo port.

I think you'd only be able to run "perl5 @" if the specified version
had already been built, but was inactive.
