Back again and I can't believe it: I have libreoffice running on my
devices- party-time :)

OK there are few things to iron out:

* java related stuff (hsqldb for embedded database in Base /
scripting): I am working on this currently and think that I don't need
help on this
* galleries: For some reason gengal fails and I've spent loads of
builds but did not understand what goes wrong so I disabled galleries
for now.

For galleries I have two questions:

1. Is the assumption correct that the contents of the galleries are
not machine specific (endian / 32/64bit)?
2. If the answer on 1. is yes: Is there a place I can download
prebuild galleries?

Thanks in advance
