www/gallery2 knob for php5-gettext missing

[Spil Oss]

When running the install of gallery2, gallery suggests to use gettext
"Your webserver does not support localization. To enable support for
additional languages please instruct your system administrator to
reconfigure PHP with the gettext option enabled."
Maybe a good idea to add that a run-dependenct to devel/php5-gettext
in the port?

Kind regards,

Spil.
