Package control and Opa does not work

[mictadlo]

Hi,
I failed to install Opa plugin for Sublime Text with help of package control in the following way. In order to install the package control you have to copy from https://sublime.wbond.net/installation#st2 the long command. Than start Sublime Text in the terminal with "sublime_text" and press "Ctrl+`" in Sublime Text and paste the command you copied from the above side. To finish the installation press enter and restart Sublime Text.

After this I did the following steps:

• $ sublime_text
• Ctrl-Shift-P and type Package Control: Install Package
• Start to type Opa and press enter on Opa.

However, I restarted many time sublime, but [View -> Syntax -> Opa] was never present. The only way to install the plugin was with the following steps:
$ cd ~/.config/sublime-text-2/Installed\ Packages/
$ wget -c https://github.com/downloads/MLstate/OpaSublimeText/Opa.sublime-package
$ Start Sublime Text with "sublime_text" and check that menu entry [View -> Syntax -> Opa] is selected.

How is it possible to install the Opa plugin through the package control?

Thank you in advance.
