Thanks Bert. Adrian, all,
Please treat me as a newbie with respect to Debian package support, but I'd like to help with this if I can. I don't currently have a Debian development system (I only have Ubuntu 15.04 on a laptop for the moment), and my time will be very limited for the next couple of weeks. That said ... The traditional Squeak VM for Etoys is actively but quietly maintained on squeakvm.org, and I personally have been using the 64-bit version for years without trouble. So aside from possible differences in the compiler toolchain in recent versions compared to the older gcc that I am currently using (gcc 4.9.2 at the moment), I am guessing that if we could refresh the sources for squeak-vm with up to date sources from squeakvm.org, then we should have a good solid VM that would support Etoys on 32-bit and 64-bit Debian. The easiest and quickest way to find out if this makes sense would be if someone with an up to date Debian 64-bit development system could try building the Squeak VM, following the instructions that I maintain at http://wiki.squeak.org/squeak/6354. If this seems to be a good approach, we would then want to trim out the portions of the source tree that are not relevant to Linux, or that should be excluded for licensing reasons. But first please try following the instructions on http://wiki.squeak.org/squeak/6354 verbatim, as this will tell us if the resulting updated VM is solid on Debian 64-bits. I should also note that the build process relies on Cmake, so that might present issues from a license perspective. I'm not sure what to do about that if it is a concern, but first things first let's see if the updated source work as expected. Thanks!
