Tried as well, modified mcexport.rb filepaths which caused a bug report error force close, tried modify loadpath rb file versions and pre ver information, still same error as original, installed ruby 1.8.6, up to latest version through all of this and none worked. Found zlib.so in all but no prevail. The simplest method of modifying mcexport load path was as close as it got to saying "hey something is there", but crash..... Back to tinkercad. Good try though, appreciate the efforts.
