Question about downgrading perl from 5.22 from 5.20

Hello,

I've learned through some searches here that mod_perl is now in the AUR, I guess because it has not kept current with perl updates.  I'm setting up a server to run ledgersmb, which heavily uses perl scripts, and requires mod_perl to be installed.   The dependencies listed for mod_perl is perl<5.22, so I'm considering downgrading perl on that machine to 5.20. 

I've downloaded perl 5.20 from the ALA, and according to https://wiki.archlinux.org/index.php/Ar … cific_date
I believe I can perform this downgrade of perl using

pacman -U perl-5.20.2-1-x86_64.pkg.tar.xz

I am relatively new to arch, and am learning the details of package management with pacman, so my question is whether or not pacman will inform me of other dependencies I may be breaking in the process of this downgrade.

Also, if there are other better workarounds for this situation, I'd be interested in learning about them.

Thanks in advance for your time.
Jerry

I'd guess downgrading perl will cause a whole bunch of issues on your system.   Does just removing the "<5.22" fix the build?

Re: Question about downgrading perl from 5.22 from 5.20

mod_perl compiles with perl-5.22 but crashes at run-time.

The truth is that mod_perl project is dead. It took more than two years to port to apache 2.4 and they still did not provide a patch for perl 5.22. In addition to perl downgrade you have two other ways:

1) avoid using mod_perl in all cost
2) ask upstream (one more time) to provide compatibility patch for perl 5.22
