in reply to Configuring Mac OS X to Install Perl Modules

You should install DateTime the same way you installed the other modules:

# from the shell / Terminal window
cpan DateTime

[download]

or within the CPAN shell as

install DateTime

[download]

DateTime needs Params::Validate as a prerequisite and the cpan program will hunt down all these prerequisites for you automatically and install them for you if you let it.

The default CPAN configuration is to ask whether to install prerequisites, but you might want to check that or change it from ask to follow so all prerequisites get installed without asking. Type in the cpan shell:

o conf prerequisites_policy

[download]

check that it's ask or follow and to set the new policy to follow type

o conf prerequisites_policy follow

[download]

Then type

o conf commit

[download]

to save the current configuration if you want it to remain.

    These posts pointed me in the write direction. Hopefully, this clarification can help someone else fix this same problem.

    To install DateTime on Mac

    1. read the original post from Perrmoss and the reply by Corion for background info
    2. sudo CPAN
    3. go through configuration (if needed) press enter for most options except:
    4. choose "follow" for the prerequisite policy (instead of ask)
    5. personally, I made the recommended/common choices to some of the options (like UNINST=1)

      6. Now here's the key:

    6. Try to install DateTime. Every time you see an error, install the package that's missing by:
      • Looking for text along the lines of

        • Can't locate Params/Validate.pm in @INC (@INC

        or

        Can't locate DateTime/Locale.pm in @INC (@INC

      • Take the "Params/Validate.pm" part and convert it to Params::Validate
      • and run the corresponding command in CPAN: install Params::Validate

    For me to get the DateTime module to install I had to run the following, first:

    install Params::Validate

    install DateTime::Locale

    install DateTime::TimeZone

    Keep following that pattern and you'll get it installed, finally!!!

      In addition to everything I wrote above, I also needed to run install Test::Exception

      So the final, full list of everything I command I ran to install DateTime on my MacBook Pro OS X 10.5.8, that has never before used perl

      1. sudo CPAN (press enter lots of times to config)
      2. install Params::Validate
      3. install DateTime::Locale
      4. install DateTime::TimeZone
      5. install Test::Exception
      6. install Test::Warn
      7. install DateTime::Format::ICal

        8. and FINALLY:

      8. install DateTime

      Sadly, I have no idea what I just did. All I know is it worked for me and I moved on to successfully finish setting up bugzilla.

      I hope this helps someone else out there (the way the posts in this thread lead me to figure this thing out)

        I also needed to install Test::More. Otherwise I got some nonsense about "You tried to run a test without a plan".

        Had to do Install Module::Runtime before everything else.

        I just wanted to say thanks, and also to let others know that almost 3 years later, this worked perfectly for me on Snow Leopard.
