my app create the following message on my CentOS 5 installation:

[root at fsisrv5 ~]# Error while loading /opt/fsi/portal/bin/fsi.psgi: 
Can't locate object method "has_hook" via package 
"Dancer2::Session::YAML" at 
/opt/fsi/portal/bin/../lib/Dancer2/Core/App.pm line 543.
Compilation failed in require at /opt/fsi/portal/bin/../lib/fsi.pm line 193.
Compilation failed in require at /opt/fsi/portal/bin/fsi.psgi line 22.
BEGIN failed--compilation aborted at /opt/fsi/portal/bin/fsi.psgi line 22.

I find the sub in Hookable.pm in line 92. So I search for the load of 
this perl module and find in App.pm following:

with qw<

I found a document for Perl-Moo (https://metacpan.org/pod/Moo#with) 
which said to me, that it define a role of a class.

At this point I stop, because I have not experience with Moo and the 
object, role and class developing.

If I run my app on a CentOS 6 or 7 installation, all work fine. So I 
think the source of the Dancer2 framework is ok.

On CentOS 5 I use perl-Moo version 1.004002 and on CentOS 6/7 a version 
2.x. On all installation I use Dancer2 0.201000 or the latest commit 
from git.

Is there a way to find out which module on CentOS 5 create the error 
above? Is this a problem with the perl-Moo module? Or I am missing 
something else (pm)?
