"Additionally cpan didn't want to install automatically. When I try "cpan install RPi-WiringPi" it returns without finding the module.

Neither cpan nor cpanm will allow you to install modules like this:

marto@shemp:~$ cpan install RPi-WiringPi

Warning: Cannot install RPi-WiringPi, don't know what it is.
Try the command

    i /RPi-WiringPi/

to find objects with matching identifiers.

marto@shemp:~$ cpan install HTML-Template

to find objects with matching identifiers.

On a related note, you could vastly reduce the time to install modules by using cpanm over cpan, it's paninful to watch cpan install modules on a Raspberry Pi. Once the dependancy wiringpi is installed cpanm RPi::WiringPi installs everything in a reasonable time for a Modeal A v1 Pi running a bunch of other stuff (apache, openvpn etc).

Update: parent updated since posting reply: adding "I finally read that you need to install WiringPi C lib first, before installing WiringPi::API. Then I also needed to manually install RPi-Pin-2.3603. Other than those glitches, it all installed fine."

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
