cpan2port: does not generate working Portfile even for own HOWTO example.

[thevlad@…]

Hi,

Trying to build Net::Curl perl port and started with cpan2port HOWTO example (wiki:howto/cpan2port). Even example fails. Why does it try to install p5.22-timedate for timedate example port?

glagol:macports vsaf$ ./cpan2port -t Date::Parse
Date::Parse is not perl porter
Date::Parse (no description available)
Date::Parse will show deps
Is it OK to try to connect to the Internet? [yes]

[ryandesign (Ryan Carsten Schmidt)]

All ports named "p5-*" are "stub" ports: they don't install anything. Their only purpose is to depend on one of the subports that actually installs something. In the case of p5-timedate here, that subport is p5.22-timedate, because perl5.22 is currently the default version of perl in MacPorts.

The reason why port build failed is that you forgot to precede that command with sudo.

[thevlad@…]

The howto does not say the build shall be made with sudo. How do I build p5.22-timedate if one is not existing?

[ryandesign (Ryan Carsten Schmidt)]

Assuming a default MacPorts installation, all builds must be done with sudo.

If you're making a new perl module port and want to install one of its subports, you can run:

sudo port install support=p5.22-something

while in the port's directory.

You might want to write to the macports-devel mailing list if you have further questions about developing portfiles.

[pixilla (Bradley Giesbrecht)]

Replying to ryandesign@…:

sudo port install support=p5.22-something

Ryans spell checker may have been too helpful, I think he meant:

sudo port install subport=p5.22-something

[thevlad@…]

I don't want to install. I want the howto to be correct for those who want to built a Portfile for perl modules.

and sudo does not help after all:

Thanx! Seems to work now.
