Building swig-rb with Ruby 4.0.3, I got this compilation error:

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']")"
]]]
This worked, thanks!
We are able to add automatically the libdir to the link options, I think.

But this didn't. The error happens during compilation of
subversion/bindings/swig/ruby/libsvn_swig_ruby/swigutil_rb.c
not during linking. It seems that the automatic fix is a bit more involved.
