Crackers2 has asked for the wisdom of the Perl Monks concerning the following question:

I'm running on SLES12, with apache 2.4.10 and mod_perl 2.0.8

In a vhost config file, I have a "PerlFixupHandler MyHandler" directive. is in /etc/apache2/script

If I do a perl -e'use MyHandler' from the commandline, everything works fine. But when it gets used from the server, it fails and is logging this in the error_log:

[Fri Aug 28 18:15:43.053198 2015] [perl:error] [pid 22133] [client x.x +.x.x:x] failed to resolve handler `MyHandler': Can't locate Digest/SH Permission denied at /etc/apache2/script/ line 7. +\nBEGIN failed--compilation aborted at /etc/apache2/script/MyHandler. +pm line 7.\nCompilation failed in require at (eval 5) line 2.\n, refe +rer: https://x.x.x.x/

If I comment out the reference to Digest::SHA, it just fails on the next module.

For debugging, I added a BEGIN block to dump INC and to try and read the file, and that does not appear to cause any errors.

This configuration used to work fine on apache 2.2 ; I did some minimal updates to the configuration files for the new authentication stuff in 2.4, but nothing related to perl.

Any idea on what's wrong and how to fix it?

Edit: Here's the start of the .pm in question:

package MyHandler; use strict; use warnings; use Apache2::Const qw(:common); use Digest::SHA qw(sha256_hex sha1_hex); use OtherModule; use Apache2::RequestRec; use Apache2::RequestIO; use Apache2::Const; use Apache2::Log; use APR::Table; use CGI::Cookie; use Apache2::URI (); use APR::URI; use APR::Pool ();
