Basically you have to spell the class name right.

Another work around could be to define "match" function:

def is_my_class( class_ ):
    if not class_.name.startswith( 'vector' ):
        return False
    n = class_.name[ len('vector' ): ]
    if 'vector' in n and 'double' in n and 'const' in n and '*' in n:
        return True
    return False

my_class = mb.class_( is_my_class )

But the prefered approach to this problem is described here:
http://language-binding.net/pyplusplus/documentation/how_to/hints.html

By the way, if you already have define to your class in C++, than
using type traits functionality could help:

from pygccxml import declarations:

mb = module_builder_t( ... )
typedef = mb.global_ns.typedef( '<<<your typedef>>>' )
my_class  = declarations.class_traits.get_declaration( typedef )
