Comment (by Hello71):

 I don't think this is correct. the gcc version has no particular relation
 to the glibc version. moreover, it may not even be installed. removing
 libraries is not a good idea, as the user may want to move their
 installation to another machine (or share it between two OSes on the same
 machine). additionally, grepping the versions is not a reliable way of
 checking ABI compatibility, as there may be missing symbols as well. the
 right-er way to do this is to build an old binary and a new binary, try to
 run the new binary on the system, and if it fails, use our library. this
 doesn't quite account for missing symbols though.
