Absolutely.  But I suggest you download the latest swig from svn, as
it contains a lot of enhancements for this.

This is how you do it in swig.

---- mystl.i ----

%module  mystl
%include std_vector.i

// GC_VALUE is a special class that knows how to mark itself.
%template(ValueVector)  std::vector< GC_VALUE >;

----- end mystl.i ----

On a console:

$ swig -ruby -c++ mystl.i      # creates mystl_wrap.cxx

Compile:

# using extconf.rb (recommended) or...

#
# posix
#
$ g++ -fPIC -DPIC -O2 mystl_wrap.cxx -o mystl_wrap.so -lruby -lstdc++

#
# Windows
#
$ vcvars32.bat
$ cl.exe -MD -LD -O2 mystl_wrap.cxx -o mystl_wrap.so /link msvcrt-
ruby1.8.dll

------ usage -----
require 'mystl'
include Mystl

a = ValueVector.new
puts a.methods  # you'll get iterators, most array methods, etc.
