in reply to CPAN.pm broken on new MacPro?

Hi thorby,

I am no cpan expert but as nobody has replied yet I thought I would give it a shot :) A couple of questions, are you logged in as root before running cpan or do you use sudo (for example: sudo cpan or sudo perl -MCPAN -e shell)? Can you post your cpan config (which is cpan> o conf just in case you don't know), It looks like part of the problem may be in retrieving 01mailrc.txt.gz and 02packages.details.txt.gz. I have read posts on newsgroups that in some cases extra command line switches have been added to things like wget which can result in problems when downloading files.

Hope this helps.

Martin

    I get the same problem when I use sudo cpan as not (I figured I shouldn't need root access for the i * query). The issue seems to be a recursive loop in /Library/Perl/5.8.6/darwin-thread-multi-2level/Compress/Zlib.pm as evidenced by the "deep recursion" message, followed by a loop which uses little CPU time but nevertheless ties up the system something fierce. When I let this run a while, it finally ends as follows: 
    Deep recursion on subroutine "Compress::Zlib::AUTOLOAD" at /Library/Pe
+rl/5.8.6/darwin-thread-multi-2level/Compress/Zlib.pm line 87.

    ...so it would appear, what is happening is a recursive loop that is eating up virtual memory until finally it fills the swap. The messages about this and that function or constant being redefined might be symptomatic or might be just noise -- however, I have never seen those on any other system, and they make me suspect there is something wrong with this installation. FWIW -- a user of the same OS level on a MacMini has no problem with cpan. Here's the o conf:
