[rt-users] rt-3.6.0pre0 "make fixdeps" fails with CPAN errors?

[Jim Meyer]

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] 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,
