If the Ruby is installed in non-standard location, it is needed to pass libdir
of Ruby using -L option to LDFLAGS for configure.
e.g.
[[[
$ ./configure ... LDFLAGS="-L$(ruby -rrbconfig -e "print
RbConfig::CONFIG['libdir']")"
]]]
We are able to add automatically the libdir to the link options, I think.
