Try 
$apt-cache search libboost

This will list the libboost options available to install from apt. If libboost-
program-options1.71-dev is not listed it is possible that there will be a
generic version libboost-program-options-dev  or libboost-program-options1.67-
dev or possibly even a more recent version if one exists. AFAIK the libboost-
program-options-dev will load the most recent available version of the library.
GC will work with v1.67 or 1,71 of libboost. Once you have identified a
candidate for libboost to install use
$sudo apt -y install libboost-program-options-dev

in a terminal and substitute the equivalent packager name if you want to install
a specific version. Alternatively 

$sudo apt -y install libboost-all-=dev 

will load all the libboost header files. (this is useful if you want to build
libboost from sources but is likely overkill otherwise).

$dpkg -l | grep libboost 

will list all the installed libboost packages on your computer. In most cases GC
will usually work with newer versions of libraries than what is specified in
README.dependencies but very occasionally an incompatible change may have been
intorduced and you may have to load an earlier version
