Can I not have the 64 bit and 32 bit packages installed at the same time?
Not on Fridays, nor when someone fumbles the builds.
It appears that an update of 32-bit binutils may be needed to allow the update. You can:
> remove the existing 32-bit binutils to allow this update to proceed, and add it back later when an update (hopefully fixed/compatible) is available.
> exclude (64-bit) binutils from this update in order to get the other stuff, and hope that the situation resolves itself soon.
In any case: the 32-bit binutils-188.8.131.52.2-17.fc11.i586 is the blocker.
