1184982 - Backport upstream bug 1174736 to bmo/4.2 to fix issue where checksetup results in an unsuccessful mod_perl install

Status: RESOLVED FIXED

(bugzilla.mozilla.org :: General, defect)

Description

[David Lawrence [:dkl]]

1) Using centos 7, install the following packages with yum:
epel-release
https://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm
aspell-devel
gcc
gcc-c++
gd-devel
gmp-devel
graphviz
httpd
ImageMagick-devel
mod_perl
mod_perl-devel
mpfr-devel
mysql-community-devel
openssl-devel
perl
perl-App-cpanminus
perl-core
perl-CPAN
perl-XML-Parser

2) ./checksetup.pl --cpanfile
3) cpanm --notest HTML::Tree Image::Magick@6.77
  -> This is necessary due to other broken deps.
4) cpanm --notest --installdeps --skip-satisfied --with-recommends --with-all-features --without-feature oracle --without-feature sqlite --without-feature pg .

Expected:
At step 4, all modules should install without error.

Actual:

Thoughts:
a) I'm presuming cpanm is installing mod_perl again since we explicitly ask for version 1, but yet the OS installed package is version 2? Which version should we be using?
b) On IRC it was implied it isn't ideal to install mod_perl via cpanm. As such, should we add a blacklist of things that export_cpanfile() excludes from the cpanfile? (on BMO we could also add the ElasticSearch module to this list for example)
