iconv causes exec unless to always return 0

[mike-lerch]

The pipe to iconv causes the unless statement to always return 0, which means the pear package is not being installed.

Example of the issue:

Mainfest:

php::pear::module { "Net_GeoIP": use_package => 'no' }

Testing:

server:~ # pear info pear.php.net/Net_GeoIP | iconv -c
No information found for `pear.php.net/Net_GeoIP'
server:~ # echo $?
0
server:~ # pear info pear.php.net/Net_GeoIP
No information found for `pear.php.net/Net_GeoIP'
server:~ # echo $?
1

Before this change: Net_GeoIP is never installed After this change: Net_GeoIP is installed
