I ran into some problems with Perl’s CPAN installer on Snow Leopard, notably, it didn’t work once Bundle::CPAN was installed. Every time I tried to install a package I’d end up with an error like this:
Catching error: 'Can\'t call method "value" on an undefined value at /System/Library/Perl/5.10.0/darwin-thread-multi-2level/IO/Uncompress/RawInflate.pm line 64. ' at /System/Library/Perl/5.10.0/CPAN.pm line 281 CPAN::shell() called at /usr/bin/cpan5.10.0 line 199
Not good. So, how to fix it? Move the broken IO::Uncompress module out of the way. In a terminal window, copy and paste the following
sudo mv /System/Library/Perl/5.10.0/darwin-thread-multi-2level/IO/Uncompress/RawInflate.pm /System/Library/Perl/5.10.0/darwin-thread-multi-2level/IO/Uncompress/RawInflate.pm-broken
Once that’s been shifted out the way, it should work provided CPAN was configured with the proper paths to your tar, bzip2 and gzip executables (if not, nuke your /System/Library/Perl/5.10.0/CPAN/Config.pm and start over).
Note: This isn’t a long-term solution, some things like CPAN::SQLite won’t install if IO::Uncompress::RawInflate is missing, but at least it gets some functionality back into CPAN. I’m very interested in hearing of any better fixes for this.
This probably broke when you did a previous install in cpan. They same issue existed in Leopard. It is a pretty well known problem.
Thanks man it works!
I encounter such a problem when i was installing bioperl with cpan on my new mac, i never met such a problem before as I was working in linux and window. This really helps.
