No idea about ftp directories etc... I usually use fpcup to get new Lazarus.
Regardless, if you're sure you called the correct Lazarus exe (with the correct primary config path, assuming you want to separate multiple Lazarus versions), a simple rebuild from the IDE tools menu works for me as well after updating Lazarus sources.
My Lazarus trunk says 1.1 and the SVN revision is around 39277... so those numbers seem ok? Have you been using a snapshot before this? If so, you are on trunk as it existed on that day.
Finally: why did you change to trunk? Are there android fixes in there?
