Bug 100874 – g-cpan: error with IO-1.20 (but it shouldn't try to install this!) while installing Catalyst

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Michele Beltrame 2005-07-31 03:09:30 UTC]

I found this problem installing Catalyst (via g-cpan -i Catalyst) on my systems
(one being x86 and the other amd64). Within the ton of modules, it tries to install:

IO-1.20

and it fails with this error:

-----

It seems to me pretty obvious that it fails, since IO 1.20 is a modules dated
1998, as it now seems to be core with in perl (in a more recent version, also).

After this fails, if I run "g-cpan -i Catalyst" it works, as it doesn't try to
install IO anymore (!!!). However, the problem comes back again when I upgrade
modules using "g-cpan -u", forcing me not to use it at all (I'm using g-cpan -i
to manually upgrade modules at this time).

I think probably there's a problem in checking that IO is already installed,
which is.

Agree completely, next version should avoid the core installed modules all together.

Re-assign, mcummings is retired...

[Comment 3 Jakub Moc (RETIRED) 2005-11-09 09:04:49 UTC]

Re-assign.

I'm installing Catalyst with "g-cpan -i Task::Catalyst". It is pulling in
perl-gcpan/IO-1.22 and this package installs without problems.

With the new IO it works for me as well, so I guss this bug can be closed...
