to:

1)Make sure the following packages are installed:
      perl (5.14 or newer) - probably preinstalled
      bzip2 - most probably preinstalled
      xdelta3 - look for a "xdelta3"-named package.
      libgmp-dev(el), The GNU Multiple Precision Arithmetic Library including header files (therefore the -dev or -devel)
      libssl-dev(el), OpenSSL Library including header files (therefore the -dev or -devel)
      A sane compilation toolchain: gcc, make
2)You want to perform the installation as root or with "sudo". After install, "chown" all files to the user you want LBC to run as. Sissy.
3)Download LBC into some suitable directory, go to that directory. e.g. via wget https://lbc.cryptoguru.org/static/client/LBC
4)Continue in section All OS.
