Hello, I have changed the building scripts a bit: - they are now split in several pretty standalone steps: a) fetching sources b) fetching existing binaries from svn c) building d) committing to SVN (not implemented yet) - there is more error checking - if some engine doesn't build, the process may still continue - it's possible to force rebuilding even if versions match - it should be possible to choose which engines to build, but option parsing is not implemented yet - there are many differences that influence Mac OS X building, but you should not bother about them anyway - buiding xetex disabled until we get support for 64-bit - it should be possible to build from any mac (at least in theory) - support for 64-bit architecture and fat binaries now from all the three relevant architectures I did that because there were constant problems when some of the steps failed to work and also because I had to modify the OS X part (why does Mac always need to be an exception? :). You may try to do svn up ./do_all.sh and report back about any problems that you might encounter. I would be grateful for any bug reports. This command will not commit to SVN yet, but there's VERSIONS.new that should be moved to VERSIONS and there is VERSIONS.svn that should be used as commit message, so the last step is almost-trivial to do manually as well, I just need to code it :) Mojca
