p5-module-build conflicts with perl5.10

[danielluke (Daniel J. Luke)]

both ports attempt to install ${prefix}/bin/config_data

[danielluke (Daniel J. Luke)]

The files are not very different:

(config_data.mp_1268319772 being the one from perl5.10)

Module::Build is already bundled with perl 5.10. If perl 5.10 is installed before a p5-module-build install is attempted, following happends:

Unfortunately, for example p5-datetime depends on p5-module-build - the perl modules are installed already by perl 5.10 but Macports does not know this

This also affects perl5.12, I noticed it when trying to install p5-perl-critic

[jmroot (Joshua Root)]

Dependent ports should probably be changed to declare the dependency as something like path:bin/config_data:p5-module-build.

Replying to jmr@…:

Dependent ports should probably be changed to declare the dependency as something like path:bin/config_data:p5-module-build.

So that would be the perl5 portgroup and

% grep p5-module-build `find . -name Portfile`
./editors/zim/Portfile:depends_lib         port:p5-gtk2 port:p5-module-build port:p5-file-mimeinfo \

[narf_tm@…]

Using path:bin/config_data:p5-module-build doesn't take the version requirement into account. A lot of these ports require a newer version of Module::Build than the one that is included with Perl.

[macports@…]

Is it possible to create a variant of p5-module-build that simply omits this file?

Since ${prefix}/bin/config_data is core perl module, it is a good idea to upgrade perl to >=5.10, remove dependecies on p5-module-build, and drop this package. Anyway, is there any reason to maintain three perl versions?

Cc Me!

[danielluke (Daniel J. Luke)]

our perl5 should probably just track the latest perl5 release (5.12 right now), but it would be simple enough for the port to not install config_data if it's already in ${prefix} as an immediate fix.

[larry+macports@…]

Suggested patch for perl5 group, to avoid p5-module-build conflict

[ghosthound]

Possibly resolved in r76485, please test.

[danielluke (Daniel J. Luke)]

yep this is OK (there are other modules that are still not ok, though - p5-archive-tar and p5-module-corelist for sure)

I don't mean to further distract from this bug, but thought this would be the best place to post that I also observe essentially the same conflict issue with p5-extutils-makemaker.

I may look into fixing the affected perl5 ports in a batch (unless others get to it before I do).
