Bugzilla Bug 237548

When using dev-perl/GD-2.41 squeezecenter won't start saying it cannot load the
GD module. Downgrading to dev-perl/GD-2.35-r1 squeezecenter will start again

Reproducible: Always

Steps to Reproduce:
1.emerge '=dev-perl/GD-2.41'
2.Restart squeezecenter
3.emerge '=dev-perl/GD-2.35-r1'
4.Start squeezecenter

Hi,

I can confirm this. BTW, if you try to start squeezecenter you get the
following error message:
==========================================
 * Starting SqueezeCenter ...
The following modules failed to load: GD

To download and compile them, please run:
/usr/share/squeezecenter/Bin/build-perl-modules.pl GD

Exiting..
 * start-stop-daemon: /usr/bin/perl died
 * Failed to start SqueezeCenter                                               
                                                                     [ !! ]
 * ERROR: squeezecenter failed to start
===========================================

But this script: 
/usr/share/squeezecenter/Bin/build-perl-modules.pl

seems to not exist anymore!

Our Gentoo ebuild builds all perl modules during install, so there should never
be a need to run such a script afterward.  In fact, that would result in
putting files in your filesystem that Gentoo could not then track, so it's not
something that should generally done on Gentoo.

Obviously, we need to look into why the latest GD version is not working. 
Also, we might want to patch squeezecenter not to issue the above message (i.e.
potentially leading people to try to manually build the perl mods).

I'll be away next week, so Stuart might know the issue, and I can get a fix
checked in in about a week if we figure it out.  In the meantime, you may be
able to apply the fix to your own overlay - and testing this would also be
helpful.  Thanks!

Patch to remove SqueezeCenter's local CPAN GD

I'll remove the reference to build-perl-modules.pl on Gentoo from the next
ebuild version - we remove that script during the Gentoo-customised install so
you should never be directed to run it.

Unfortunately, GD is one perl module that SqueezeCenter does not build during
the installation process - there's an open bug for this which I've prodded in
the hope that this can change
(http://bugs.slimdevices.com/show_bug.cgi?id=6143). This is the reason
dev-perl/GD is a dependency of the ebuild.

The short-term fix is for you to not unmask dev-perl/GD-2.41 (it's currently
marked unstable, so I think you must be intentionally pulling that in).

The reason for the failure is a bug in the current ebuild; it brings in
Gentoo's GD (since it needs the binary part of that perl module due to the
aforementioned SC bug), but leaves the non-binary part in SqueezeCenter's local
CPAN tree. This is fine if Gentoo's binary bits match the version in Gentoo's
CPAN tree, but with 2.41 installed that's not the case.

The longer-term fix is to remove the GD bits from the SqueezeCenter CPAN tree
during the installation - the attached patch does that.

Joe, I've made this change to my 7.3.0 development version so it'll be it the
next ebuild version I send to you. I'm also away for the next week,
coincidentally.

Stuart, thanks!

OK, I have applied your patch to both 7.1.0 and 7.2.0 - and I changed the
comment to reflect that it fixes this bug.  Seems like the most straightforward
fix.

Both are checked in as -r1.

squeezecenter-7.2.0 works fine with the newer GD here :-)
