Rt-3.6.0pre0 "make fixdeps" fails with CPAN errors?

Hello!

Starting with a fresh RHEL3 WS box, built and installed Perl 5.8.6 and
mod_perl 2.0.2, did the usual CPAN config-ery including an “install
Bundle::CPAN” which got me to CPAN v1.87, then tried “make fixdeps” for
the first time and got a pile of errors:

% make fixdeps

In more bizarre news, while trying to eliminate the problem, I dropped
back to CPAN 1.86, 1.85, then 1.76, during which I got issues like this:

[…]

I discovered that if I just run “cpan” at this point and do “install
Exception::Class”, it all works just fine (for CPAN 1.76 and 1.87).
Bizarre.

If it’s useful, I can fairly quickly revert to the fresh install plus
perl 5.8.6 (and even add the mod_perl stuff, too) to track this down.

Any thoughts?

Cheers!

Hello!

The short story:

make fixdeps doesn’t play nice on RHEL3 WS using perl 5.8.6 due to
something odd about how calling cpan Foo::Bar differs from
CPAN::Shell->install('Foo::Bar'). You can setenv RT_FIX_DEPS_CMD cpan to work around this issue.

The saga:

So after Jesse pointed out that I’d not configured cpan by running it
once, I went back to duplicate this again, without the spurious errors
from CPAN.

So again, fresh RHEL3 WS box, Perl 5.8.6, mod_perl 2.0.2 installed. I
did make sure cpan was configured this time; I didn’t update
Bundle::CPAN, so it’s v1.76 which comes with Perl 5.8.6. I still see the
build/tmp error, which doesn’t seem to happen if I work directly in a
cpan shell:

make fixdeps

make: *** [fixdeps] Error 17

I immediately ran cpan and typed install Cache::Cache and it worked
fine. When I tried make fixdeps again, the next module succeeded, but
the one after failed due to the tmp directory’s insistence on existing.

For grins, I read the rt-test-dependencies code and discovered I could
use RT_FIX_DEPS_CMD to control how fixdeps fixes deps. When I set that
to ‘cpan’, everything went swimmingly.

So it seems that CPAN::Shell->install(‘foo’) differs from cpan foo
who knew?

FYI’ly yours,
