I am trying to install svn_access_manager-0.5.6.4. on turnkeylinux which is based on debian, I have tried on 2 versions of linux based on wheezy and jessie.

After I press Start installation I get following

Warning: Header may not contain more than a single header, new line detected in /usr/share/svn-access-manager/svn_access_manager/include/db-functions-adodb.inc.php on line 363

Any ideas what's wrong?

Thank You for Your help in advance.
