Question

Answer 1

A:

It would appear that MooseX::Declare does not list the module named aliased as a dependency, while using it. Try install aliased from the CPAN shell, then try installing MooseX::Declare again.

I've sent a pull request to the author to get the dependency list updated. But FWIW, you almost certainly had some install failures before this point, as many other things require this module.

@Ether: How many is "many"? Without doing any sort of comprehensive analysis, and just going by what I have installed on a couple of my boxes here ("a lot"), I can see a bunch of Catalyst modules, as well as `MooseX-Role-WithOverloading`, that's all.

Grrrr 2010-08-17 22:30:35

Grrrr: some things MooseX::Declare depends on also depend on `aliased`, for example Parse::Method::Signatures and MooseX::Method::Signatures. I am hoping Kaeso sends his install logs.

Ether 2010-08-17 22:40:56

vanilla CPAN.pm sometimes refuses to give up when it should, which means that one module fails, and then you get another three or four modules that depended on it also failing and cluttering up the log. Very frustrating.

I seem to have the aliased installed and updated allready:cpan[2]> install aliased /aliased is up to date (0.30).

Answer 2

A:

I had similar problems a few days ago, on OS X. In my case, either MooseX::Method::Signatures or MooseX::Declare depended on B::Hooks::OP::Check. Once I installed that, all problems went away.

@Pedro: did you report this issue?

Ether 2010-08-17 23:24:35

No I didn't. I attributed to problem to OS X, since I've never had any issues on Linux. But now, seeing this post, there might something to it, if course. I'd be helpful to know if the poster is also on OS X.

Nope, ubuntu 10.04

Answer 3

A:

I have resolved this issue, with good advice from Ether. What happened is that the YAML prerequesite was not installed/not installed properly. What I did is to start over by deleting the build folder and reinstalling:

$ sudo rm /home/jfb/.cpan/build -rf
$ sudo cpan > cpan.log
cpan[1]> install YAML
cpan[2]> install MooseX::Declare

Now everything seems to work, see the log file here.

Kaeso 2010-08-18 00:15:24

Do not run `sudo cpan` because the tests will run with superuser privileges. This is a bad thing. Instead, setup [`make_install_make_command` and `mbuild_install_build_command`](http://p3rl.org/CPAN#Config_Variables) so the privileges are only elevated for the time when they are really needed: for installing into a system location.
