Got lost for few months in company projects and lot of travelling.
Now is more time to care about ST again, but noticed that "svn://tron.homeunix.org/simutrans/simutrans/trunk --username anon" will not work anymore. Did not follow up complete now.
What is actually the working checkout command?
Also the exact make command incl. parameters to know would be very helpful.
I am not programmer even joined some courses about. But this has been 25 years ago

In fact I am working with MacBook Pro (early 2011 series) and think it should be possible to follow up al the advices above.
Once I get it working, it shall be possible to provide a working OSX release (with better performance than the cross compiled one) at least once a month, always related to the latest nightly.
I am offering my support in this way, please help to make it happen.
