The build instructions linked to from that page are helpful too. The only
snag I hit was that I first built the most recent version of Mozilla,
which is not compatible with the XForms code. You need to check out the
1.9.1 Mozilla code, and then everything works fine.
I'm not a Mac user - I had to borrow a laptop to get this done - so I
can't provide regular snapshots. But hopefully someone will find this
useful. There have been a few people asking about Mac builds on the list
I have to give the Mac back tomorrow, so if anyone notices any problems
that I could fix, then please let me know.
