Error installing Storable: t/restrict fails with 'COWs do not become read-only'

[boxofrox]

I use dclone() in my perl script and get an "AutoLoader can't find auto/Storable/dclone.al" error. So I'm trying to install the Storable-2.29 module using CPAN, which compiles, but fails on make test.

My system is Ubuntu 11.04.
I've compiled perl-5.8.8 into /usr/local/perl5.8.8 (my company standardizes on 5.8.8, I have no choice on this).

I'm failing to sort this out on my own.
Does anyone know what COW is? (copy on write?)
Any ideas what would cause a COW to not be read-only?
Should I be using an older version of Storable with perl5.8.8? Can you point to a specific version?

If my perl5.8.8 compile options may be the cause, please specify which option you want. My config.sh is 1043 lines and I don't want to spam the thread.

(Edit) Tried >cpan Storable from perl-5.10 (installed with apt-get) and all tests passed

Go ahead and download it with CPAN using force install. Also, see: Re: Is it possible to use IPC COW with Perl?.

[boxofrox]

I used the force install Storable to install the module. I haven't figured out the copy-on-write test failure.

However, the error that led me down this path--Autoloader not finding dclone.al--was solved by moving use Storable qw(dclone); to the top of my use list instead of the bottom. I have no idea why this worked, but I've moved past this topic for now.

Thanks for the suggestions and replies.

You are correct that COW means “copy on write.”   I’m afraid I can”t help you beyond that.   (What makes a read-only COW?   Dunno... did somebody forget to milk her?   Did she spot a Chick Fil-A road sign?)
