Bug#804358: Install issue with x86_64?

[Matt Nottingham]

Package: python-guiqwt
Version: 2.3.1-1
Severity: normal

When I try to install python-guiqwt it appears to clash with libstdc++ and 
hence won't let it be installed.

I get (from aptitude 0.7.4):

 * libstdc++6:i386 breaks python-guiqwt (<=2.3.1-1)

Does it just require relinking?

Thanks,

Matt
