before installing all bt, check if all needed bt paths are present on the file

system. This change permit to not waste time in case of missing bt (you don't
have to wait for all previous bt to be installed to get the error message) and
the time cost of this operation is negligible (less than 0.007 seconds for 52
bt on my 2 cores 2Gb Ram machine)
