[TYPO3-linux] Typo3 6.2 beta3 installation complaining about links

[David Apltauer]

Hello,

I am following the Typo3 6.2 beta 3 install instructions at
https://github.com/TYPO3/TYPO3.CMS/blob/master/INSTALL.md however in the
first step of the installation the install tool complains (all are errors):

    Path /index.php is not a link
    The target /index.php should be a link, but is of type file. This can
not be fixed. Please investigate.

    Path /typo3 is not a link
    The target /typo3 should be a link, but is of type dir. This can not be
fixed. Please investigate.

    /typo3_src should be a link, but it does not exist
    Links can not be fixed by this system

    PHP OpenSSL extension not working
    Something went wrong while trying to create a new private key for
testing. Please check the integration of the PHP OpenSSL extension and if
it is installed correctly.

The folder structure is as follows:

    htdocs
      typo3
        .htaccess
        index.php -> ./typo3_src/index.php
        typo3 -> ./typo3_src/typo3/
        typo3_src -> ../typo3_src-6.2.0-beta3/
      typo3_src-6.2.0-beta3

I run the installation via accessing host/typo3/. The environment is Apache
on Linux. I have already tried to change links from xyz/ to xyz but that
makes no difference. It seems the links should be okay, why the error
messages in the install tool?
