Re^3: cpan: unable to install modules

[Bloodnok]

...either that, or you've got yourself a broken perl install.

Do you have LWP installed elsewhere on your system, if so, try adding the path to it [LWP] to your PERL5LIB and running the install again.

$ sudo find / -name PERL5LIB

The first module I tried to install with cpan while using my system's 5.8.6 perl was LWP::Simple. However, cpan couldn't get past the "make test" step during installation. So someone told me to download and install libww-perl-5.833 by hand, and just skip the 'make test' step and do "make" followed by "make install". After I did that, I was able to use LWP::Simple in my perl programs.

Then I tried to install my second module, FileUtils::More, using cpan, and once again cpan couldn't install the module. In response, I decided to upgrade to perl 5.10.1. The location of my new perl 5.10.1 install is shown in my initial post. Anyway, that's why some of the results in my find searches are in a Perl/5.8.6/ directory and some are in a perl5/perl5.10.1/ directory

PERL5LIB is an environment variable, not a module, and should be set to 'point to' the location of the alternate library location(s) (if any) such that the command perl -V should contain a list of all the standard library locations for your installation together with any alternate locations.

Since neither /Library/Perl/5.8.6 or /System/Library/Perl/5.8.6 are standard locations, I would infer that PERL5LIB isn't being used, as it ought, to do its job - what you need, I'm guessing, is something like:

PERL5LIB=$PERL5LIB:/Library/Perl/5.8.6:/System/Library/Perl/5.8.6
export PERL5LIB

Just a thought, but where is FileUtils::More? I checked CPAN but couldn't find it:-)

I don't see anything set for an environment variable named PERL5LIB:

$ echo $PERL5LIB

Can you explain this statement:

Since neither /Library/Perl/5.8.6 or /System/Library/Perl/5.8.6 are standard locations, I would infer that PERL5LIB isn't being used, as it ought, to do its job - what you need, I'm guessing, is something like:

PERL5LIB=$PERL5LIB:/Library/Perl/5.8.6:/System/Library/Perl/5.8.6
export PERL5LIB

Why would I want anything to point to my system's install of perl 5.8.6 when I want to use my own install of perl 5.10.1?

Thanks.
