File::Temp

I just upgraded the Red Hat system that RT 3.8.8 is running on. Upon reboot, RT would not stop and was complaining that my File::Temp was at 0.16 and needed to be at 0.18. So I upgraded to 0.22 and now RT will still not start. The error message in the httpd log is:

Unknown error\nCompilation failed in require at (eval 2) line 1.\n

I have loaded 0.18 and things are still down.

Any ideas or any more information needed?

Thanks,

More than likely, the upgrade broke the Scalar::Util perl module. From a
CPAN prompt, do:

force install Scalar::Util

This should reinstall the Scalar::Util perl module over what the Redhat
upgrade just installed…

Hit it right on the head.

Ran the force install Scalar::Util and all is well.

How did you know that this was the issue?

The breaking of File::Temp and Scalar::Util after upgrading Perl on Red Hat-based systems has been discussed quite a few times over the years. With Scalar::Util, the version installed by the upgrade is up to date, but how it’s compiled by the package maintainers is the issue.

I have never had any problem with RHEL5 perl updates breaking
Scalar::Util, but I do keep a separate File::Temp package installed
outside of the perl package:

locate File/Temp.pm

/usr/lib/perl5/5.8.8/File/Temp.pm
/usr/lib/perl5/vendor_perl/5.8.8/File/Temp.pm

rpm -qf /usr/lib/perl5/5.8.8/File/Temp.pm

/usr/lib/perl5/vendor_perl/5.8.8/File/Temp.pm
perl-5.8.8-32.el5_5.1.x86_64
perl-File-Temp-0.20-1.rhel5.noarch

My whole rt install is not done with CPAN, but with rpms that I mostly
got from EPEL, Fedora and a few odd ones, like perl-File-Temp from DAG.
I find this a lot easier than having CPAN and rpm fight each other
over package updates. From a sysadmin point of view, I like having
everything installed via rpms.
