Summary: [ruby] aliases broken with -minherit

Initial Comment:
It appears that %alias is broken with the -minherit flag.

I discovered it when binding a vector. One way that this elicits itself is that the STL vector bindings use
%alias.  It will segfault in registration with a NameError relating to reject!

AFACS, this stl binding broke on Ruby between 1.3.29 and 1.3.33, since the newer binding uses some ruby
aliases.  (I use Ubuntu and one version is Dapper's and the other is Hardy's)

The fix is pretty simple (this is against 1.3.36, but is equally applicable to other versions):
