Re: What have I forgotten about specifying which Perl should be /opt/local/bin/perl?

[Gabriel Rosenkoetter]

Aha!




And that's neat, but:

[58] (gr@wedge:~)% which perl
/opt/local/bin/perl
[59] (gr@wedge:~)% ls -l `!!`
ls -l `which perl`
lrwxr-xr-x  1 root  admin  8 Dec  6  2020 /opt/local/bin/perl -> perl5.28
[60] (gr@wedge:~)%

And `port select --summary` is still just Python stuff:

[60] (gr@wedge:~)% port select --summary
Name     Selected  Options
====     ========  =======
pip      pip37     pip3-apple none
pip2     none      none
pip3     none      pip3-apple none

python2  none      python27 python27-apple none
python3  python37  python37 python38-apple python39 none
[61] (gr@wedge:~)% sudo port select --list perl

Error: The 'list' command failed: The specified group 'perl' does not exist.
[62] (gr@wedge:~)% sudo port select --list perl5

[63] (gr@wedge:~)% sudo port select --set perl perl5.34

[64] (gr@wedge:~)% sudo port select --set perl5 perl5.34

[65] (gr@wedge:~)%



For example, is the user expected to create their own perl (or perl5) group?





I just did this for now:

[69] (gr@wedge:~)% sudo ln -sf /opt/local/bin/perl5.34 /opt/local/bin/perl
Password:
[70] (gr@wedge:~)% which perl
/opt/local/bin/perl
[71] (gr@wedge:~)% perl --version

But I expect that'll bite me in the ass when I upgrade the perl5 port…?

Does the Perl port not support version selection this way, or am I still not remembering the right way to do this? Shouldn't installing the port at least plug some defaults in for those entries? I'm eminently aware that Perl and Python behave differently wrt module support, but shouldn't MacPorts at least try to provide a consistent interface across them?

I just did a `sudo port install perl5.34`, anticipating that doing so would "activate" it (and the build output indicated that step was taken), presumably bumping the /opt/local/bin/perl sym link to the new version and… apparently that was the wrong thing to assume, since that sym link no longer exists on this system?

What am I forgetting here?

(If so, why'd it get removed by installing a new version?)
