If the launcher isn't opening, check the locale (type locale in terminal). If the output has these two lines: locale: Cannot set LC_CTYPE to default locale: No such file or directory locale: Cannot set LC_ALL to default locale: No such file or directory ...
Open the terminal and run this: export LC_ALL="en_US.UTF-8"

The package version is the version of the launcher bootstrap - the part that actually downloads and updates the launcher.
That means the version number of the actual launcher (2.x.xxx) is different from the version here (9xx+) on a fundamental level, and should not be compared.
The package is outdated only when the bootstrap version you get here is different from the bootstrap version you would get from minecraft.net when using the raw tarball.
