When I try to run Blender builds from Graphicall.org (11.04 Natty 64-bit), I get the following message:

./blender: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version 'GLIBCXX_3.4.15' not found (required by ./blender)

I have tried updating GCC and G++, but it still gives the error, and when I run

strings /usr/lib/x86_64-linux-gnu/libstdc++.so.6 | grep GLIBC

I get

GLIBCXX_3.4 

GLIBCXX_3.4.1

GLIBCXX_3.4.2

GLIBCXX_3.4.3

GLIBCXX_3.4.4

GLIBCXX_3.4.5

GLIBCXX_3.4.6

GLIBCXX_3.4.7

GLIBCXX_3.4.8

GLIBCXX_3.4.9

GLIBCXX_3.4.10

GLIBCXX_3.4.11

GLIBCXX_3.4.12

GLIBCXX_3.4.13

GLIBCXX_3.4.14

GLIBC_2.2.5

GLIBC_2.3

GLIBC_2.4

GLIBC_2.3.4

GLIBC_2.3.2

GLIBCXX_FORCE_NEW

GLIBCXX_DEBUG_MESSAGE_LENGTH

Are there any other libraries needed to get glib 3.4.15 on 11.04, or any other workarounds?

Edit: I don't know if it makes a difference, but I'm on a Wubi install.

ldd ./blender gives
