I tend to disabling the version check. liblzma5 has a proper symbols
file which is used by dh_shlibdeps/dpkg-shlibdeps, so we should be
safe, I guess.

Probably ...

eval {
    require XSLoader;
    XSLoader::load('Compress::Raw::Lzma', $XS_VERSION);
    1;
} 
or do {
    require DynaLoader; 
    local @ISA = qw(DynaLoader);
    bootstrap Compress::Raw::Lzma $XS_VERSION ; # ← line 165
};
