By the time you have enough materials to start putting in block form you should have a compressor, I don't see what the big deal is... Machine block, circuit and stone... Not that hard
I respect your desire to make your game an absurb grinding process and unnecessary hurdle, you might enjoy your game this way and please take note that most players dislike this type of game and it is their right to request GTech add-on to be non-intrusive add-on both for it's parent mod and other mods.
Most of the Minecraft players, play it in order to take the edge off, not to jump between machines and grind like there is no tomorrow.
Current settings of GTech add-on is locking most of the FTB players out of the servers, some are sticking with Direwolf20 pack and some are just removing GTech add-on from their single player games and staying away from servers. All these hurdle could be solved with only one line in config files to turn on-off mod interaction and keeping interaction off by default.
In order to clarify things, please do not tell me that GTech add-on has configuration for interaction; only 1 out of 100 will go through such a tedious task and default on causes many server admins to follow it unwillingly.
I do hope, FTB Mod Pack steam will change the pack to a GTech interaction off config, I have little to no hope that Gregor himself would see the bigger picture and fix the mistake he has made or at least add an interaction on/off switch for all options.
In the end, I respect your gaming tastes and request the same for the more casual majority that is playing Minecraft with and without FTB packs.
