:-(

> Anyway, should our builds avoid referencing external resources not under our control?  Or would it be be better to copy the required tar files to a server our community controls, (either files.opensmalltalk.org or file.pharo.org)?

I don’t see how the former is possible :-(. Do some variation of the latter is necessary.  I like your suggestion of files.pharo.org; files.opensmalltalk.org doesn’t exist and do would need funding.  I think adding the tar files to opensmalltalk-vm itself would be a huge mistake; it would cause the repository to bloat quite quickly right?  So what are the logistics of using files.pharo.org?
